If you have already spent several weeks or months doing physiotherapy but your shoulder still hurts when you:

• Lift your arm
• Reach overhead
• Reach behind your back
• Sleep on the affected side
• Carry something
• Exercise
• Put on clothing

it is reasonable to ask:

Why am I not getting better?

Physiotherapy is often one of the first treatments used for shoulder problems, particularly rotator cuff-related pain. Exercises tailored to the problem can improve strength and flexibility, and many rotator cuff problems can be managed without surgery.

But if progress has stalled, the answer is not always:

“Just do more physiotherapy.”

Sometimes the rehabilitation programme needs to change.

Sometimes the diagnosis needs to be reconsidered.

And sometimes ultrasound, X-ray or MRI may provide useful additional information.

How Long Should Shoulder Physiotherapy Take to Work?

There is no single timetable.

The NHS notes that shoulder pain can sometimes take months to settle and that shoulder exercises may be continued for several weeks. It also advises reassessment if pain continues after physiotherapy sessions have finished.

The more useful question is:

Are you actually improving?

Signs of progress may include:

• Less night pain
• Better sleep
• Greater range of movement
• Easier dressing
• Better overhead reach
• Increased strength
• Less pain carrying objects
• Better tolerance of exercise

If you have completed many sessions but none of these things are changing, reassessment may be appropriate.

Why Might Physiotherapy Not Be Working?

There are several possibilities.

1. The Original Diagnosis May Need to Be Reconsidered

“Shoulder pain” is not one diagnosis.

Possible causes include:

• Rotator cuff tendinopathy
• Rotator cuff tear
• Bursitis
• Frozen shoulder
• Arthritis
• Biceps tendon problems
• Labral problems
• Pain referred from the neck
• Other musculoskeletal conditions

Different problems may require different rehabilitation strategies.

2. There May Be a Rotator Cuff Tear

A rotator cuff injury can range from irritation to a partial or complete tendon tear.

Possible clues include:

• Pain lifting the arm
• Night pain
• Weakness
• Difficulty reaching overhead
• Difficulty reaching behind your back

Mayo Clinic notes that rotator cuff injuries may produce pain that worsens at night and that significant tendon injury can lead to weakness and impaired shoulder function.

If you have completed appropriate rehabilitation but significant weakness remains, further assessment may be useful.

3. You May Have Frozen Shoulder

Frozen shoulder can sometimes initially be mistaken for another shoulder problem.

Typical features include:

• Increasing pain
• Progressive stiffness
• Difficulty raising the arm
• Difficulty reaching behind the back
• Night pain

The important feature is true restriction of movement.

If your shoulder is getting progressively stiffer despite therapy, the diagnosis may need to be reconsidered.

4. The Exercise Programme May Be Too Aggressive

More exercise is not always better.

If every physiotherapy session results in:

• Much worse night pain
• Several days of increased pain
• Reduced movement
• Greater difficulty using the arm

the current loading may exceed what the shoulder tolerates.

The programme may need changes to:

• Resistance
• Repetitions
• Range of movement
• Frequency
• Exercise selection

The aim is progressive improvement rather than repeatedly creating major flares.

5. The Rehabilitation May Not Be Progressive Enough

The opposite can also occur.

If you have been doing the same very light exercises for months, the shoulder may never regain enough capacity for:

• Carrying
• Lifting
• Gym exercises
• Sports
• Overhead work

A rehabilitation programme often needs gradual progression as symptoms improve.

6. The Pain May Be Coming From Your Neck

Not all shoulder pain originates in the shoulder.

Cervical nerve irritation can sometimes cause:

• Shoulder pain
• Arm pain
• Tingling
• Numbness
• Weakness

If symptoms extend into the forearm or hand, or if neck movement changes your shoulder or arm pain, the cervical spine may also need to be assessed.

What if My Shoulder Is Still Painful After 6 to 8 Weeks?

Persistent symptoms do not automatically mean something serious is wrong.

But they can justify asking:

• Is the diagnosis correct?
• Has strength objectively improved?
• Is the shoulder becoming stiff?
• Is a tendon tear possible?
• Is the neck contributing?
• Would imaging change the treatment plan?

The NHS recommends medical reassessment when shoulder pain is not improving, including after physiotherapy.

What if Physiotherapy Makes the Shoulder Worse?

A small temporary increase in discomfort can occur after rehabilitation.

But repeated major worsening may mean the plan should change.

It is worth reassessing if physiotherapy consistently causes:

• Severe night pain
• Increasing weakness
• Reduced movement
• Difficulty sleeping
• Reduced ability to use the arm

The aim should be an improving trend over time.

Should I Stop Physiotherapy?

Not necessarily.

The next step may be to:

• Modify the exercise programme
• Reduce or change the load
• Reassess the diagnosis
• Obtain imaging
• Add another treatment
• Change the rehabilitation approach

Physiotherapy may still be useful even if the original programme was not producing enough progress.

Should I See a Doctor?

A medical reassessment may be useful if:

• Pain remains significant
• You cannot raise the arm normally
• Night pain persists
• Weakness is increasing
• The shoulder is becoming more restricted
• Physiotherapy has not helped
• There was a significant injury

A shoulder assessment typically includes examination of:

• Range of movement
• Strength
• Tenderness
• Painful movements

Mayo Clinic notes that physical examination and strength testing are important in assessing rotator cuff injuries.

Do I Need an X-Ray?

An X-ray may be useful when the doctor wants to assess:

• Arthritis
• Bone abnormalities
• Fracture
• Certain structural changes

However, a rotator cuff tear itself is not directly shown well on ordinary X-ray.

Mayo Clinic notes that X-rays can help identify other causes such as arthritis or bone spurs, while tendon assessment requires other imaging.

Is Ultrasound Useful?

Yes.

Ultrasound can assess:

• Rotator cuff tendons
• Muscles
• Biceps tendon
• Bursa

One advantage is that structures can be examined while the shoulder moves.

Mayo Clinic notes that ultrasound can visualise shoulder muscles and tendons dynamically and compare the painful shoulder with the other side.

When Is MRI Useful?

MRI provides a more comprehensive view of the shoulder.

It can show:

• Rotator cuff tendons
• Muscles
• Labrum
• Biceps tendon
• Bone
• Joint structures
• Surrounding soft tissue

RadiologyInfo notes that shoulder MRI provides detailed images of the bones, tendons and muscles and is particularly useful for assessing rotator cuff tears and other shoulder injuries.

MRI may become particularly useful when:

• Physiotherapy has not helped
• Significant weakness remains
• A rotator cuff tear is suspected
• The diagnosis remains unclear
• A procedure or surgery is being considered
• There may be more than one structure involved

MRI vs Ultrasound: Which Is Better?

They answer slightly different questions.

Ultrasound May Be Useful For:

• Rotator cuff tendons
• Biceps tendon
• Bursa
• Dynamic assessment
• Focused tendon evaluation

MRI May Be Useful For:

• Rotator cuff tears
• Labral problems
• More comprehensive joint assessment
• Multiple possible causes
• Persistent unexplained symptoms
• Surgical planning

The best test depends on the clinical question.

Does Shoulder MRI Use Radiation?

No.

MRI uses a magnetic field and radiofrequency energy rather than ionising radiation.

What if MRI Shows a Rotator Cuff Tear?

A rotator cuff tear does not automatically mean surgery.

Treatment depends on:

• Tear size
• Whether the injury was traumatic
• Age
• Weakness
• Functional demands
• Duration
• Response to treatment

Mayo Clinic notes that conservative treatment such as physical therapy may be enough for some rotator cuff injuries, while more severe injuries may require surgical consideration.

What if MRI Shows No Major Tear?

That can still be useful information.

A shoulder can remain painful because of:

• Tendon irritation
• Bursa irritation
• Joint stiffness
• Load sensitivity
• Other musculoskeletal causes

A scan does not need to show a dramatic tear for symptoms to be real.

Treatment should still be based on the clinical findings.

Does Failed Physiotherapy Mean I Need Surgery?

No.

Many patients can still be managed without surgery.

Non-surgical treatment may include:

• Modified physiotherapy
• Activity adjustment
• Medication where appropriate
• Selected injections
• Progressive strengthening

Mayo Clinic notes that non-surgical treatment is effective in many rotator cuff cases.

Can an Injection Help?

In selected patients, a shoulder injection may help reduce symptoms enough to:

• Sleep better
• Move more comfortably
• Participate in rehabilitation

However, it is not automatically appropriate for everyone.

Mayo Clinic notes that corticosteroid injections can provide temporary relief when pain interferes with sleep, daily activities or therapy, while also noting that repeated steroid exposure can weaken tendons.

The decision should therefore be individualised.

When Is Surgery More Likely to Be Considered?

Surgical assessment may become more relevant when there is:

• A major traumatic tear
• Significant persistent weakness
• Persistent disability
• Failure of appropriate conservative treatment
• A structural problem that is unlikely to respond sufficiently to rehabilitation alone

A surgical decision should take into account the symptoms, physical examination and imaging rather than the scan result alone.

What if My Shoulder Is Becoming More Stiff?

Increasing stiffness raises the possibility of conditions such as frozen shoulder.

If you are progressively losing the ability to:

• Raise your arm
• Reach behind your back
• Dress normally
• Comb your hair

the treatment strategy may need to change.

What if My Shoulder Pain Is Mainly at Night?

Night pain commonly occurs with rotator cuff problems.

Mayo Clinic notes that rotator cuff pain may worsen at night.

Persistent night pain despite appropriate rehabilitation can be another reason to reassess the diagnosis and consider whether imaging would add useful information.

What if I Suddenly Became Weak After an Injury?

Sudden weakness after:

• Falling
• Lifting something heavy
• A sports injury
• A forceful pull

raises greater concern about a significant tendon injury.

This deserves earlier assessment than gradually developing mild shoulder pain.

Frequently Asked Questions About Shoulder Pain Not Improving After Physiotherapy

How long should I try physiotherapy?

There is no fixed number of sessions. What matters is whether movement, strength, pain and function are trending in the right direction.

Why might physiotherapy not be helping?

Possible reasons include an incomplete diagnosis, excessive or insufficient loading, a rotator cuff tear, frozen shoulder, referred neck pain or another shoulder condition.

Should I have an ultrasound?

Ultrasound can be useful for assessing rotator cuff tendons, the biceps tendon and bursa.

Should I get an MRI?

Not automatically. MRI becomes more useful when symptoms persist despite treatment, significant weakness is present, a tear is suspected or imaging may change management.

Can MRI show a rotator cuff tear?

Yes. MRI provides detailed images of the rotator cuff and other shoulder structures.

Does a rotator cuff tear always need surgery?

No. Many patients can be managed non-surgically depending on the tear and symptoms.

Can injections help if physiotherapy is too painful?

They can help selected patients temporarily, particularly when pain interferes with sleep or rehabilitation, but they are not appropriate for everyone.

How much does shoulder MRI cost?

A shoulder MRI arranged through The Pain Relief Clinic is currently approximately S$1,000, including the scan images and formal radiologist’s report.

Important Medical Information

This article provides general educational information and does not replace an individual medical consultation.

Lack of improvement with physiotherapy does not necessarily mean that physiotherapy was inappropriate or that MRI, injections or surgery are required. The appropriate next step depends on symptoms, shoulder strength, range of movement, trauma history, duration, previous treatment and examination findings.

Seek prompt medical attention for severe shoulder pain after significant trauma, visible deformity, sudden swelling, sudden inability to raise the arm or major new weakness.
