Shoulder Impingement: Causes, Symptoms, Treatment & Recovery

Shoulder Impingement: Causes, Symptoms, Treatment & Recovery

If your shoulder hurts when you reach overhead, put on a shirt, reach behind your back, or sleep on your side, you may have been told that you have shoulder impingement.

You may also have heard terms such as:

• Shoulder impingement syndrome
• Subacromial impingement
• Rotator cuff impingement
• Subacromial pain syndrome

But what actually causes it?

Do you have a bone “pinching” your tendon?

Do you need an MRI?

Can shoulder impingement heal without surgery?

And how long does recovery take?

The good news is that most shoulder pain associated with so-called impingement can be managed successfully without surgery.

At Restorative Touch Physiotherapy on Hamilton Mountain, we assess the entire shoulder rather than focusing on one structure or one painful movement. Treatment typically involves improving your shoulder’s ability to tolerate load, restoring strength and gradually returning you to the activities you enjoy.

This guide explains what shoulder impingement means, why it happens, what treatment actually involves, which exercises can help, and when you should seek further medical assessment.

What Is Shoulder Impingement?

“Shoulder impingement” is commonly used to describe pain around the shoulder that occurs with certain movements, particularly lifting the arm.

Historically, the idea was that a tendon was being physically “pinched” between the top of the upper-arm bone and part of the shoulder blade.

We now understand shoulder pain to be considerably more complicated than simply having something being pinched.

Pain can be influenced by:

• Tendon sensitivity
• Muscle strength
• Training or activity load
• Shoulder movement
• Previous injury
• Sleep
• Stress
• General pain sensitivity
• How quickly you’ve increased activity

This is why two people can have very similar shoulder symptoms but require completely different treatment plans.

Is Shoulder Impingement Actually a Pinched Tendon?

Not necessarily.

This is one of the most important updates in how we understand shoulder pain.

Your shoulder is constantly moving and adapting.

Pain during an overhead movement does not automatically mean that a tendon is being damaged or trapped.

You can experience pain even when there isn’t significant structural damage.

Likewise, imaging can show changes in the rotator cuff or other shoulder structures in people who have no pain whatsoever.

That’s why a physiotherapy assessment looks at your symptoms, movement, strength and function, rather than assuming that an imaging finding explains everything.

What Does Shoulder Impingement Feel Like?

Common symptoms include pain:

• At the front or side of the shoulder
• When reaching overhead
• When reaching across your body
• When putting on or removing clothing
• When reaching behind your back
• During lifting
• During sports involving the arm
• When lying on the affected shoulder

You may also notice weakness or a feeling that the shoulder isn’t working normally.

Pain can range from mild irritation to significant discomfort that interferes with daily activities.

What Is a Shoulder Impingement Painful Arc?

A painful arc refers to pain that occurs during a particular portion of shoulder elevation.

Some people experience pain as they raise their arm overhead and then notice it decreases as the arm reaches a higher position.

This pattern can provide useful information during an assessment.

However, a painful arc by itself does not prove that you have a specific structural problem.

A physiotherapist will consider it alongside your strength, range of motion, symptoms and other examination findings.

What Causes Shoulder Impingement?

There usually isn’t one single cause.

Shoulder pain can develop when the demands placed on the shoulder exceed its current capacity.

This can happen after:

A sudden increase in activity

For example, you suddenly start:

• Weightlifting
• Swimming
• Tennis
• Pickleball
• Throwing
• Painting
• Renovating

Repetitive overhead activity

Repeatedly using the shoulder overhead can increase the load on the rotator cuff and surrounding tissues.

Weakness or reduced capacity

If the shoulder hasn’t been exposed to much resistance, a sudden increase in demand can exceed its current capacity.

Previous injury

A previous shoulder injury can alter how you move and load the shoulder.

Reduced recovery

Poor sleep, stress and insufficient recovery can influence how your body responds to physical load.

Can Poor Posture Cause Shoulder Impingement?

Posture is often blamed for shoulder pain.

But the relationship isn’t that simple.

There isn’t one “bad posture” that automatically causes shoulder impingement.

You can sit with excellent posture and still develop shoulder pain.

You can also spend time with your shoulders rounded forward without developing shoulder problems.

Instead of trying to maintain perfect posture all day, it’s generally more useful to:

Move regularly.

Change positions.

Build strength.

Gradually expose your shoulder to the activities you want to perform.

Can Sleeping on Your Shoulder Cause Impingement?

Sleeping on a painful shoulder can certainly make symptoms worse.

When you lie directly on the affected shoulder, you may place additional pressure through already sensitive tissues.

If sleeping on your shoulder hurts, try:

• Sleeping on the opposite side
• Supporting the painful arm with a pillow
• Sleeping on your back
• Using pillows to find a more comfortable position

You don’t necessarily have to stop sleeping on that side forever.

As your shoulder becomes stronger and less sensitive, you may be able to return to it.

Does Shoulder Impingement Mean I Have a Rotator Cuff Tear?

No.

Shoulder impingement and rotator cuff tears are not the same thing.

Rotator cuff problems exist along a spectrum.

Someone may have shoulder pain without a significant tear.

Someone else may have a partial tear.

Another person may have a full-thickness tear.

Importantly, structural changes on imaging don’t always correlate perfectly with symptoms.

This is why an assessment is important before assuming that shoulder pain means you’ve torn something.

Do I Need an MRI for Shoulder Impingement?

Usually, an MRI isn’t the first step for straightforward shoulder pain.

A thorough history and physical examination can often provide substantial information.

Imaging may become appropriate when:

• Symptoms aren’t improving as expected
• A significant traumatic injury occurred
• There is substantial weakness
• A serious structural injury is suspected
• The diagnosis is uncertain
• Further medical management is being considered

Your healthcare provider can determine whether imaging is appropriate.

Can Shoulder Impingement Heal on Its Own?

It can improve, particularly when the aggravating activity is modified and the shoulder is gradually reloaded.

However, “rest until it goes away” isn’t always the best strategy.

If you completely stop using your shoulder, you may temporarily reduce pain but fail to rebuild the capacity required for your normal activities.

A better approach is usually:

Reduce aggravating loads → maintain comfortable movement → progressively strengthen → gradually return to normal activity.

How Long Does Shoulder Impingement Take to Heal?

Recovery varies considerably.

Milder cases may improve over several weeks.

More persistent shoulder problems can take several months.

Your recovery may depend on:

• How long you’ve had symptoms
• How irritable your shoulder is
• Your activity level
• Your strength
• Whether there was an injury
• Your rehabilitation program
• Sleep and recovery
• How consistently you complete your exercises

A useful way to think about recovery is not simply:

“When will the pain be gone?”

Instead ask:

“Can I do more than I could a few weeks ago?”

Improved strength, movement and activity tolerance are signs that you’re moving in the right direction.

Can Physiotherapy Fix Shoulder Impingement?

Physiotherapy can be very effective for managing many types of shoulder pain.

The focus is usually not on “putting the shoulder back into place.”

Instead, treatment may involve:

• Strengthening the rotator cuff
• Strengthening the shoulder blade muscles
• Improving shoulder capacity
• Improving mobility when needed
• Modifying aggravating activities
• Gradually returning to overhead activity
• Education about pain and recovery

Your program should be based on your individual assessment.

The Most Important Part of Shoulder Rehabilitation: Exercise

Exercise is one of the most important components of shoulder rehabilitation.

Your shoulder is designed to handle load.

If you want to return to:

• The gym
• Swimming
• Tennis
• Pickleball
• Golf
• Work
• Overhead lifting
• Recreational activities

your shoulder needs to progressively regain the capacity to tolerate those demands.

Shoulder Impingement Exercises

There isn’t one magic exercise.

A good rehabilitation program progresses over time.

Here are examples of exercises that may be appropriate depending on your symptoms and current strength.

Exercise 1: Isometric External Rotation

Stand beside a wall with your elbow bent approximately 90 degrees.

Place the back of your hand against the wall.

Gently push your hand into the wall without actually moving your arm.

Hold for approximately 5–10 seconds.

Relax.

Repeat 5–10 times.

Why use it?

It can introduce rotator cuff loading without requiring significant shoulder movement.

If it increases your pain significantly, stop and speak with your physiotherapist.

Exercise 2: Band External Rotation

Attach a resistance band to a secure point.

Keep your elbow close to your body.

Rotate your forearm outward while keeping your elbow near your side.

Slowly return to the starting position.

Try:

2–3 sets of 8–15 repetitions.

The resistance should be challenging without causing a significant increase in symptoms.

Exercise 3: Scaption

Hold a light weight in each hand.

Raise your arms approximately 30–45 degrees away from your body rather than directly out to the side.

Raise the weights to a comfortable height.

Slowly lower them.

Try:

2–3 sets of 8–12 repetitions.

Start light.

The goal is to gradually build capacity rather than prove how much weight you can lift.

Exercise 4: Wall Slides

Stand facing a wall.

Place your forearms against the wall.

Slowly slide your arms upward.

Move through a comfortable range.

Slowly return.

Try:

2–3 sets of 8–12 repetitions.

If the movement is painful, reduce the range or modify the exercise.

Exercise 5: Progressive Overhead Press

Eventually, many people with shoulder pain need to return to overhead loading.

Start with a light resistance.

Press overhead through a comfortable range.

Gradually increase the weight and repetitions as your symptoms allow.

This is particularly important if your goal is to return to:

• Weightlifting
• Work overhead
• Sport
• Recreational activities

Your final rehabilitation shouldn’t stop at pain-free basic movements.

It should prepare you for the activities you actually want to do.

Should Shoulder Impingement Exercises Hurt?

This is an important question.

Exercise does not necessarily have to be completely pain-free.

A small amount of discomfort during rehabilitation may be acceptable for some people.

However, you shouldn’t force through severe pain.

A useful approach is to monitor how you respond during the exercise and afterward.

If your symptoms become significantly worse and remain aggravated for a prolonged period, the exercise or workload may need to be modified.

Your physiotherapist can help establish appropriate symptom guidelines for your specific condition.

Should I Rest My Shoulder?

Relative rest can be helpful.

Complete rest usually isn’t necessary.

If overhead lifting is painful, temporarily reducing overhead loading may make sense.

But continue using your shoulder within a tolerable range.

The goal is to maintain movement and gradually rebuild capacity.

Think:

Modify → don’t immobilize.

Should I Avoid Overhead Exercises?

Not necessarily.

Overhead movement is not inherently bad for your shoulder.

If overhead activity is currently painful, you may need to temporarily reduce the amount, intensity or frequency.

Then gradually increase it as your capacity improves.

Avoiding overhead movement indefinitely can actually make returning to overhead activity more difficult.

Can You Still Work With Shoulder Impingement?

Often, yes.

Your ability to work depends on your symptoms and job demands.

Someone working at a desk may need very different modifications from someone who:

• Works in construction
• Paints
• Installs equipment
• Lifts overhead
• Works in a warehouse
• Performs repetitive manual tasks

A physiotherapist can help modify your workload while you recover.

Can You Exercise at the Gym With Shoulder Impingement?

In many cases, yes.

You may need to temporarily modify:

• Weight
• Repetitions
• Range of motion
• Exercise selection
• Frequency

For example, you may tolerate a light dumbbell press but not a heavy overhead press.

That doesn’t mean you can never overhead press again.

It means your current capacity isn’t ready for that particular load.

What About Push-Ups?

Push-ups aren’t automatically bad for shoulder pain.

They can actually be useful as part of a progressive strengthening program.

If regular push-ups hurt, you can modify them by:

• Using a wall
• Using an elevated surface
• Reducing repetitions
• Adjusting hand position
• Progressing gradually

As your strength improves, the exercise can become more challenging.

What About Bench Press?

Bench pressing may be possible with shoulder pain, but technique and loading matter.

You may need to temporarily reduce:

• Weight
• Range of motion
• Volume
• Frequency

Your physiotherapist can help determine what modifications are appropriate.

Do Shoulder Impingement Exercises Need to Strengthen the Rotator Cuff?

Often, yes.

The rotator cuff plays an important role in shoulder function.

Strengthening the rotator cuff can help improve the shoulder’s ability to tolerate load.

But rehabilitation shouldn’t necessarily consist of endless tiny band exercises.

Eventually, your program should progress to exercises that reflect your actual goals.

If you want to return to lifting heavy weights, your rehabilitation needs to eventually involve meaningful resistance.

Do I Need Manual Therapy?

Manual therapy can be useful for some people.

It may include:

• Joint mobilization
• Soft-tissue techniques
• Massage
• Movement-based techniques

These treatments can sometimes help temporarily reduce pain or improve movement.

But manual therapy shouldn’t be the only component of rehabilitation.

The long-term goal is to improve your ability to move and load your shoulder independently.

What About Shockwave Therapy?

Shockwave therapy is sometimes used for persistent tendon-related pain.

Whether it is appropriate depends on the specific diagnosis and your clinical presentation.

It shouldn’t automatically be used simply because your shoulder hurts.

Your physiotherapist can assess whether shockwave therapy is appropriate and whether it should be combined with exercise-based rehabilitation.

What About Acupuncture or Dry Needling?

Acupuncture or dry needling may provide symptom relief for some people.

However, they should generally be considered adjunctive treatments rather than replacements for rehabilitation.

If your goal is to regain shoulder strength and return to activity, your shoulder ultimately needs to become capable of tolerating those activities.

Do Cortisone Injections Help Shoulder Impingement?

Corticosteroid injections can provide short-term symptom relief for some shoulder conditions.

They may be considered when pain is significantly interfering with sleep or rehabilitation.

However, injections aren’t necessarily a permanent solution.

If pain returns after the injection, the underlying rehabilitation and activity-management strategy still matters.

Discuss injections with your physician or appropriate healthcare provider.

Does Shoulder Impingement Require Surgery?

Usually, surgery isn’t the first treatment for uncomplicated shoulder pain.

Most people are initially managed with conservative treatment such as:

• Exercise
• Activity modification
• Education
• Pain management
• Progressive strengthening

Surgery may be considered when there is a specific structural problem, significant trauma, persistent weakness or symptoms that fail to improve with appropriate conservative care.

Your healthcare provider can determine whether surgical consultation is appropriate.

What Happened to Shoulder Decompression Surgery?

Historically, surgery was sometimes performed to remove part of the bone thought to be causing impingement.

Research has challenged the idea that simply creating more space under the acromion reliably improves outcomes for typical subacromial shoulder pain.

This is one reason modern shoulder rehabilitation tends to focus more heavily on:

progressive exercise + load management + restoring function

rather than assuming that the shoulder needs to be surgically “opened up.”

Can Shoulder Impingement Become a Rotator Cuff Tear?

Shoulder pain and rotator cuff tears can coexist, but one doesn’t automatically progress into the other.

A painful shoulder isn’t necessarily a shoulder that’s being progressively damaged.

However, significant weakness following trauma or persistent loss of function should be assessed.

Can Shoulder Impingement Cause Permanent Damage?

In most cases, shoulder pain doesn’t mean your shoulder is being permanently damaged every time it hurts.

Pain is a protective output from your nervous system and doesn’t directly tell you how much tissue damage exists.

That doesn’t mean pain should be ignored.

It means pain needs to be interpreted alongside your history, examination and functional abilities.

How Do I Prevent Shoulder Impingement From Coming Back?

The best prevention strategy isn’t avoiding shoulder movement.

It’s building capacity.

Strengthen regularly

Maintain rotator cuff and upper-body strength.

Increase activity gradually

Don’t suddenly go from no overhead activity to several hours of repetitive overhead work.

Manage training volume

Increase weights, repetitions and frequency progressively.

Maintain general fitness

Your overall physical capacity matters.

Don’t ignore recurring symptoms

If shoulder pain repeatedly returns, identify what’s driving it rather than repeatedly waiting for it to disappear.

A Simple Shoulder Recovery Progression

Your rehabilitation may look something like this:

Stage 1: Calm symptoms

Modify activities that significantly aggravate the shoulder.

Maintain comfortable movement.

Begin appropriate low-load exercises.

Stage 2: Build strength

Progressively strengthen the rotator cuff and surrounding musculature.

Stage 3: Increase load

Increase resistance, repetitions and range of motion.

Stage 4: Return to overhead activity

Gradually reintroduce overhead work, lifting or sport.

Stage 5: Return to full capacity

Train at the intensity required for your lifestyle or sport.

The exact timeline varies.

The important principle is progressive loading.

When Should You See a Physiotherapist?

Consider booking an assessment if:

• Your shoulder pain has lasted more than a few weeks.
• You have difficulty lifting your arm.
• Shoulder pain is affecting your sleep.
• You can’t exercise normally.
• You have recurring shoulder pain.
• You have weakness.
• You aren’t sure what’s causing the pain.
• Home exercises haven’t helped.
• You’re worried about a rotator cuff tear.
• You want to return to sport or overhead work safely.

The sooner you understand what’s driving the problem, the easier it can be to develop an appropriate plan.

When Should You See a Doctor?

Shoulder pain following significant trauma should be assessed.

You should also seek medical assessment if you experience:

• Sudden significant weakness
• Inability to lift your arm following an injury
• Significant deformity
• Severe swelling
• Persistent unexplained pain
• Fever or feeling unwell alongside severe shoulder pain
• Numbness or neurological symptoms

These symptoms may indicate something other than routine shoulder pain.

Frequently Asked Questions About Shoulder Impingement

What is shoulder impingement?

Shoulder impingement is a commonly used term for pain associated with shoulder movement, particularly overhead activity. Modern understanding recognizes that shoulder pain is more complex than simply a tendon being physically pinched.

What does shoulder impingement feel like?

It commonly causes pain around the front or side of the shoulder, especially when reaching overhead, lifting, dressing or lying on the affected side.

Can shoulder impingement heal without surgery?

Yes. Many people improve with conservative treatment involving activity modification, exercise and progressive strengthening.

How long does shoulder impingement take to heal?

Milder cases may improve over several weeks, while persistent cases can take several months. Recovery depends on the severity and duration of symptoms and how the shoulder responds to rehabilitation.

Do I need an MRI for shoulder impingement?

Not usually as a first step. A clinical assessment can often provide useful information. Imaging may be appropriate when symptoms are unusual, severe, traumatic or not improving as expected.

Is shoulder impingement the same as a rotator cuff tear?

No. They are different conditions, although they can occur together.

Should I rest my shoulder?

Relative rest can help reduce aggravating loads, but complete rest is usually unnecessary. Gradually rebuilding shoulder capacity is an important part of recovery.

Should I avoid overhead exercises?

Not permanently. If overhead movement is painful, temporarily modify the load or range and gradually work back toward overhead activity.

Can I go to the gym with shoulder impingement?

Often, yes. You may need to modify exercises, weights, range of motion and training volume while your shoulder recovers.

Can push-ups make shoulder impingement worse?

They can aggravate symptoms if the current load exceeds your capacity, but push-ups can also become a useful strengthening exercise when appropriately modified and progressed.

Is shoulder impingement caused by bad posture?

Not necessarily. Posture can influence symptoms, but there isn’t one “bad posture” that automatically causes shoulder pain.

Is sleeping on my shoulder bad?

If lying on the affected shoulder increases your pain, try another position or support the arm with a pillow.

Can physiotherapy help shoulder impingement?

Yes. Physiotherapy can help restore shoulder strength, movement and tolerance to activity while providing strategies for managing symptoms.

Do I need surgery?

Most uncomplicated shoulder pain is initially treated without surgery. Surgical assessment may be appropriate in specific situations, such as significant traumatic injury, substantial weakness or symptoms that don’t improve with appropriate conservative care.

• Works in construction
• Paints
• Installs equipment
• Lifts overhead
• Works in a warehouse
• Performs repetitive manual tasks

A physiotherapist can help modify your workload while you recover.

Can You Exercise at the Gym With Shoulder Impingement?

In many cases, yes.

You may need to temporarily modify:

• Weight
• Repetitions
• Range of motion
• Exercise selection
• Frequency

For example, you may tolerate a light dumbbell press but not a heavy overhead press.

That doesn’t mean you can never overhead press again.

It means your current capacity isn’t ready for that particular load.

What About Push-Ups?

Push-ups aren’t automatically bad for shoulder pain.

They can actually be useful as part of a progressive strengthening program.

If regular push-ups hurt, you can modify them by:

• Using a wall
• Using an elevated surface
• Reducing repetitions
• Adjusting hand position
• Progressing gradually

As your strength improves, the exercise can become more challenging.

What About Bench Press?

Bench pressing may be possible with shoulder pain, but technique and loading matter.

You may need to temporarily reduce:

• Weight
• Range of motion
• Volume
• Frequency

Your physiotherapist can help determine what modifications are appropriate.

Do Shoulder Impingement Exercises Need to Strengthen the Rotator Cuff?

Often, yes.

The rotator cuff plays an important role in shoulder function.

Strengthening the rotator cuff can help improve the shoulder’s ability to tolerate load.

But rehabilitation shouldn’t necessarily consist of endless tiny band exercises.

Eventually, your program should progress to exercises that reflect your actual goals.

If you want to return to lifting heavy weights, your rehabilitation needs to eventually involve meaningful resistance.

Do I Need Manual Therapy?

Manual therapy can be useful for some people.

It may include:

• Joint mobilization
• Soft-tissue techniques
• Massage
• Movement-based techniques

These treatments can sometimes help temporarily reduce pain or improve movement.

But manual therapy shouldn’t be the only component of rehabilitation.

The long-term goal is to improve your ability to move and load your shoulder independently.

What About Shockwave Therapy?

Shockwave therapy is sometimes used for persistent tendon-related pain.

Whether it is appropriate depends on the specific diagnosis and your clinical presentation.

It shouldn’t automatically be used simply because your shoulder hurts.

Your physiotherapist can assess whether shockwave therapy is appropriate and whether it should be combined with exercise-based rehabilitation.

What About Acupuncture or Dry Needling?

Acupuncture or dry needling may provide symptom relief for some people.

However, they should generally be considered adjunctive treatments rather than replacements for rehabilitation.

If your goal is to regain shoulder strength and return to activity, your shoulder ultimately needs to become capable of tolerating those activities.

Do Cortisone Injections Help Shoulder Impingement?

Corticosteroid injections can provide short-term symptom relief for some shoulder conditions.

They may be considered when pain is significantly interfering with sleep or rehabilitation.

However, injections aren’t necessarily a permanent solution.

If pain returns after the injection, the underlying rehabilitation and activity-management strategy still matters.

Discuss injections with your physician or appropriate healthcare provider.

Does Shoulder Impingement Require Surgery?

Usually, surgery isn’t the first treatment for uncomplicated shoulder pain.

Most people are initially managed with conservative treatment such as:

• Exercise
• Activity modification
• Education
• Pain management
• Progressive strengthening

Surgery may be considered when there is a specific structural problem, significant trauma, persistent weakness or symptoms that fail to improve with appropriate conservative care.

Your healthcare provider can determine whether surgical consultation is appropriate.

What Happened to Shoulder Decompression Surgery?

Historically, surgery was sometimes performed to remove part of the bone thought to be causing impingement.

Research has challenged the idea that simply creating more space under the acromion reliably improves outcomes for typical subacromial shoulder pain.

This is one reason modern shoulder rehabilitation tends to focus more heavily on:

progressive exercise + load management + restoring function

rather than assuming that the shoulder needs to be surgically “opened up.”

Can Shoulder Impingement Become a Rotator Cuff Tear?

Shoulder pain and rotator cuff tears can coexist, but one doesn’t automatically progress into the other.

A painful shoulder isn’t necessarily a shoulder that’s being progressively damaged.

However, significant weakness following trauma or persistent loss of function should be assessed.

Can Shoulder Impingement Cause Permanent Damage?

In most cases, shoulder pain doesn’t mean your shoulder is being permanently damaged every time it hurts.

Pain is a protective output from your nervous system and doesn’t directly tell you how much tissue damage exists.

That doesn’t mean pain should be ignored.

It means pain needs to be interpreted alongside your history, examination and functional abilities.

How Do I Prevent Shoulder Impingement From Coming Back?

The best prevention strategy isn’t avoiding shoulder movement.

It’s building capacity.

Strengthen regularly

Maintain rotator cuff and upper-body strength.

Increase activity gradually

Don’t suddenly go from no overhead activity to several hours of repetitive overhead work.

Manage training volume

Increase weights, repetitions and frequency progressively.

Maintain general fitness

Your overall physical capacity matters.

Don’t ignore recurring symptoms

If shoulder pain repeatedly returns, identify what’s driving it rather than repeatedly waiting for it to disappear.

A Simple Shoulder Recovery Progression

Your rehabilitation may look something like this:

Stage 1: Calm symptoms

Modify activities that significantly aggravate the shoulder.

Maintain comfortable movement.

Begin appropriate low-load exercises.

Stage 2: Build strength

Progressively strengthen the rotator cuff and surrounding musculature.

Stage 3: Increase load

Increase resistance, repetitions and range of motion.

Stage 4: Return to overhead activity

Gradually reintroduce overhead work, lifting or sport.

Stage 5: Return to full capacity

Train at the intensity required for your lifestyle or sport.

The exact timeline varies.

The important principle is progressive loading.

When Should You See a Physiotherapist?

Consider booking an assessment if:

• Your shoulder pain has lasted more than a few weeks.
• You have difficulty lifting your arm.
• Shoulder pain is affecting your sleep.
• You can’t exercise normally.
• You have recurring shoulder pain.
• You have weakness.
• You aren’t sure what’s causing the pain.
• Home exercises haven’t helped.
• You’re worried about a rotator cuff tear.
• You want to return to sport or overhead work safely.

The sooner you understand what’s driving the problem, the easier it can be to develop an appropriate plan.

When Should You See a Doctor?

Shoulder pain following significant trauma should be assessed.

You should also seek medical assessment if you experience:

• Sudden significant weakness
• Inability to lift your arm following an injury
• Significant deformity
• Severe swelling
• Persistent unexplained pain
• Fever or feeling unwell alongside severe shoulder pain
• Numbness or neurological symptoms

These symptoms may indicate something other than routine shoulder pain.

Frequently Asked Questions About Shoulder Impingement

What is shoulder impingement?

Shoulder impingement is a commonly used term for pain associated with shoulder movement, particularly overhead activity. Modern understanding recognizes that shoulder pain is more complex than simply a tendon being physically pinched.

What does shoulder impingement feel like?

It commonly causes pain around the front or side of the shoulder, especially when reaching overhead, lifting, dressing or lying on the affected side.

Can shoulder impingement heal without surgery?

Yes. Many people improve with conservative treatment involving activity modification, exercise and progressive strengthening.

How long does shoulder impingement take to heal?

Milder cases may improve over several weeks, while persistent cases can take several months. Recovery depends on the severity and duration of symptoms and how the shoulder responds to rehabilitation.

Do I need an MRI for shoulder impingement?

Not usually as a first step. A clinical assessment can often provide useful information. Imaging may be appropriate when symptoms are unusual, severe, traumatic or not improving as expected.

Is shoulder impingement the same as a rotator cuff tear?

No. They are different conditions, although they can occur together.

Should I rest my shoulder?

Relative rest can help reduce aggravating loads, but complete rest is usually unnecessary. Gradually rebuilding shoulder capacity is an important part of recovery.

Should I avoid overhead exercises?

Not permanently. If overhead movement is painful, temporarily modify the load or range and gradually work back toward overhead activity.

Can I go to the gym with shoulder impingement?

Often, yes. You may need to modify exercises, weights, range of motion and training volume while your shoulder recovers.

Can push-ups make shoulder impingement worse?

They can aggravate symptoms if the current load exceeds your capacity, but push-ups can also become a useful strengthening exercise when appropriately modified and progressed.

Is shoulder impingement caused by bad posture?

Not necessarily. Posture can influence symptoms, but there isn’t one “bad posture” that automatically causes shoulder pain.

Is sleeping on my shoulder bad?

If lying on the affected shoulder increases your pain, try another position or support the arm with a pillow.

Can physiotherapy help shoulder impingement?

Yes. Physiotherapy can help restore shoulder strength, movement and tolerance to activity while providing strategies for managing symptoms.

Do I need surgery?

Most uncomplicated shoulder pain is initially treated without surgery. Surgical assessment may be appropriate in specific situations, such as significant traumatic injury, substantial weakness or symptoms that don’t improve with appropriate conservative care.
