Frozen Shoulder: Symptoms, Stages, Exercises and Treatment Options

Frozen shoulder, or adhesive capsulitis, causes shoulder pain and progressive stiffness that can make everyday movements surprisingly difficult. Reaching overhead, putting on a shirt or jacket, washing your hair, or reaching behind your back may gradually become harder.

One of the most important features of frozen shoulder is that both pain and shoulder movement become restricted. The limitation is not simply discomfort when moving the arm. As the condition progresses, the shoulder can become genuinely stiff.

Frozen shoulder usually develops gradually. Pain may be more noticeable at first, followed by increasing stiffness. Later, pain may settle while movement remains restricted before gradually improving. Recovery varies considerably between individuals and can take months or, in some cases, years.

What Does Frozen Shoulder Feel Like?

The classic combination is shoulder pain plus progressive loss of movement.

You may notice:

• Pain that develops gradually
• Pain that is worse at night or affects sleep
• Increasing shoulder stiffness
• Difficulty raising your arm
• Difficulty reaching behind your back
• Trouble putting on or removing clothing
• Difficulty washing or styling your hair
• Reduced ability to rotate your arm
• Increasing difficulty with everyday activities

A particularly useful clinical feature is restricted external rotation, although other shoulder movements can also become limited.

Because several shoulder conditions can cause pain and stiffness, these symptoms alone do not confirm frozen shoulder. A clinical assessment is needed to distinguish adhesive capsulitis from other causes of shoulder pain.

What Actually Happens in a Frozen Shoulder?

Frozen shoulder affects the capsule surrounding the shoulder joint.

The capsule normally allows the shoulder to move through a large range of motion. In adhesive capsulitis, the capsule becomes inflamed and progressively tightens, contributing to pain and restricted movement.

This explains why frozen shoulder can feel different from ordinary muscle soreness.

The problem is not simply that a muscle feels tight. The shoulder joint itself can lose a substantial amount of movement.

What Causes Frozen Shoulder?

The cause of frozen shoulder is not always clear.

Some cases develop without an obvious trigger, often referred to as primary or idiopathic frozen shoulder.

Other cases occur after something has affected normal shoulder movement. This is sometimes described as secondary frozen shoulder.

Possible associations include:

• Previous shoulder injury
• Shoulder surgery
• Prolonged immobilisation
• Diabetes
• Thyroid disorders
• Some other medical conditions

Having a risk factor does not mean that you will develop frozen shoulder. Some people develop the condition without an identifiable cause.

Who Is More Likely to Develop Frozen Shoulder?

Frozen shoulder is particularly common in middle age, with many cases occurring between approximately 40 and 60 years.

Diabetes is an important associated condition. Other systemic conditions, including thyroid disorders, have also been associated with adhesive capsulitis.

However, frozen shoulder is not exclusively an age-related condition, and risk factors cannot be used on their own to diagnose it.

What Are the 3 Stages of Frozen Shoulder?

Frozen shoulder is commonly described in three stages:

1. Freezing stage
2. Frozen stage
3. Thawing stage

These stages are useful for understanding the general progression, but they are not a precise timetable. Symptoms and recovery can vary significantly from one person to another.

1. Freezing Stage: Pain and Increasing Stiffness

During the freezing stage, pain tends to become more prominent.

You may notice that:

• Shoulder pain gradually increases
• Movement becomes painful
• Night pain affects sleep
• Certain positions become difficult
• Shoulder movement gradually decreases

As the shoulder becomes painful, people often use the arm less. This can make everyday movement increasingly difficult.

2. Frozen Stage: Stiffness Becomes the Main Problem

During the frozen stage, pain may become less intense while stiffness remains significant.

You may find it particularly difficult to:

• Reach overhead
• Reach behind your back
• Put on a jacket
• Fasten clothing
• Wash your hair
• Perform certain gym exercises

The amount of movement can remain restricted even when the pain is no longer as severe as it was initially.

3. Thawing Stage: Movement Gradually Returns

During the thawing stage, shoulder mobility gradually improves.

This process can be slow. Improvement does not necessarily happen evenly from week to week, and the final amount of movement regained varies between individuals.

How Long Does Frozen Shoulder Last?

There is no fixed recovery time for frozen shoulder.

Some people improve over several months, while others experience symptoms for considerably longer. NHS guidance notes that frozen shoulder can take months or years to get better.

This is one reason why comparing your recovery directly with someone else’s can be misleading.

The goal of treatment is generally to manage symptoms, maintain appropriate movement and function, and support recovery according to the individual’s presentation.

Frozen Shoulder vs Other Shoulder Problems

Not every painful or stiff shoulder is frozen shoulder.

Frozen Shoulder

Typically involves:

• Progressive pain
• Significant stiffness
• Restricted active and passive movement
• Difficulty with shoulder rotation
• Increasing difficulty with everyday activities

Rotator Cuff-Related Shoulder Pain

May cause:

• Pain during certain arm movements
• Pain when lifting the arm
• Pain with resisted movements
• Possible weakness

The pattern is different from the global restriction typically seen with frozen shoulder.

Shoulder Arthritis

Can also cause pain and stiffness and may need to be considered during assessment.

This is why self-diagnosing frozen shoulder from symptoms alone can be unreliable. A clinician may need to assess your movement, strength, history and other possible causes.

How Is Frozen Shoulder Diagnosed?

Frozen shoulder is primarily diagnosed through a clinical assessment.

A physiotherapist or doctor may assess:

• When your symptoms started
• How the pain behaves
• Active shoulder movement
• Passive shoulder movement
• External rotation
• Shoulder flexion and elevation
• Functional activities
• Relevant medical history
• Previous injury or surgery

Imaging is not necessarily required to diagnose frozen shoulder. However, an X-ray or other investigation may sometimes be used to rule out alternative causes of shoulder pain and stiffness.

The important point is that there is no single test that should be used in isolation.

What Is the Best Treatment for Frozen Shoulder?

There is no single treatment that is appropriate for every person with frozen shoulder.

Management depends on factors such as:

• Stage of the condition
• Pain severity
• Shoulder mobility
• Functional limitations
• Irritability of symptoms
• Medical history
• Response to previous treatment

Current evidence does not establish one universally superior conservative treatment. Recent research highlights variation in treatment outcomes and the importance of interpreting evidence carefully.

Treatment may include physiotherapy, exercises, pain management and, for some patients, medical interventions such as corticosteroid injection.

Can Physiotherapy Help Frozen Shoulder?

Yes. Physiotherapy can be part of the management of frozen shoulder, particularly when the goal is to maintain or gradually improve movement and function.

A physiotherapist may use:

• Individualised mobility exercises
• Gentle stretching
• Progressive strengthening
• Manual therapy where appropriate
• Education about the condition
• Activity modification
• Home exercises
• Gradual return to normal activities

The programme should change according to the patient’s symptoms and tolerance.

For example, a highly irritable shoulder may require a different approach from a shoulder that is less painful but significantly stiff.

Recent evidence also suggests that different manual mobilisation approaches can produce improvements in pain, disability and range of motion, although the evidence base continues to evolve.

Should You Stretch a Frozen Shoulder?

Gentle movement can be helpful, but forcing a painful shoulder is not necessarily better.

During the more painful stage, aggressive stretching may increase symptoms. As irritability decreases, the rehabilitation programme can gradually progress towards improving range of motion and strength.

The NHS advises keeping the shoulder moving but avoiding strenuous self-prescribed exercises that aggravate the condition.

This is why a frozen shoulder exercise programme should ideally be based on your current symptoms and movement restrictions rather than copied from a generic routine.

Frozen Shoulder Exercises

Depending on your symptoms and stage of recovery, a physiotherapist may recommend exercises such as:

Pendulum Exercise

Lean forward while supporting yourself with your unaffected arm. Allow the affected arm to hang comfortably and make small, gentle movements.

Purpose: Provides gentle shoulder movement without requiring significant active lifting.

Wall or Finger Walks

Use your fingers to gradually walk the affected arm upward on a wall.

Purpose: Helps work gradually on shoulder elevation.

Table Slides

Place your hand or forearm on a table and gently slide it forward within a comfortable range.

Purpose: Provides controlled movement while reducing some of the load on the shoulder.

Assisted Rotation

Your unaffected arm or a suitable exercise tool may help the affected shoulder move through a comfortable rotational range.

Purpose: Helps maintain or gradually improve shoulder rotation.

Important: Exercises should be adjusted according to pain, stiffness and irritability. If an exercise significantly increases your symptoms, discuss it with a healthcare professional rather than repeatedly forcing the movement.

Can Frozen Shoulder Go Away Without Treatment?

Frozen shoulder can improve naturally over time, but recovery can be prolonged.

That does not mean that every person should simply wait for the condition to disappear.

Appropriate management can help with pain, movement, function and day-to-day activities while the shoulder progresses through recovery. NHS guidance includes gentle exercise and physiotherapy as treatment options.

Can Frozen Shoulder Happen Again?

It is possible for frozen shoulder to affect the other shoulder.

People with certain associated conditions, particularly diabetes, may have a greater risk of developing adhesive capsulitis.

If you previously had frozen shoulder and begin developing similar progressive pain and stiffness in either shoulder, an assessment can help determine whether it is the same condition or another shoulder problem.

When Should You See a Physiotherapist?

Consider a professional assessment if:

• Shoulder pain is persistent
• Your shoulder is becoming progressively stiffer
• You are losing the ability to reach overhead
• Reaching behind your back has become difficult
• Pain is affecting your sleep
• Dressing or personal care has become difficult
• You are unable to continue normal exercise or work activities

You should also seek medical assessment if the shoulder problem began after significant trauma, if you suddenly cannot move the arm, or if you have other concerning symptoms.

Persistent shoulder pain and stiffness should not automatically be assumed to be frozen shoulder because several conditions can produce similar symptoms.

What Happens During Frozen Shoulder Physiotherapy?

A physiotherapy appointment should begin with assessment rather than immediately starting exercises.

Your physiotherapist may first look at:

Your history: When the pain started, how it has changed and what activities affect it.

Your movement: How far the shoulder can move actively and passively.

Your function: Which everyday activities, work tasks, exercise or sports have become difficult.

Your symptoms: Whether pain, stiffness or both are currently the dominant problem.

The treatment programme can then be adjusted according to these findings.

This is particularly important because frozen shoulder does not behave identically throughout its course.

Frozen Shoulder Treatment in Dubai

If persistent shoulder pain and stiffness are affecting your sleep, work, exercise or everyday activities, an assessment can help determine whether frozen shoulder is likely and what management options may be appropriate.

At Scandinavian Physiotherapy Center DMCC in JLT, Dubai, physiotherapy for frozen shoulder may include clinical assessment, education, mobility exercises, strengthening, manual therapy where appropriate and a personalised home programme.

The approach is adapted to your symptoms, movement restrictions, functional goals and stage of recovery rather than applying the same exercise programme to every patient.

Frozen Shoulder: Key Takeaway

Frozen shoulder is more than ordinary shoulder pain. The combination of progressive pain and significant restriction of shoulder movement is what makes adhesive capsulitis distinctive.

Recovery can be slow, and there is no single treatment or exercise programme that suits everyone. Appropriate assessment can help distinguish frozen shoulder from other causes of shoulder pain and guide management according to the individual’s symptoms and stage of recovery.

If persistent shoulder pain or stiffness is making everyday movement difficult, consider getting the shoulder assessed rather than simply waiting for it to improve.
