Frozen Shoulder: Causes, Symptoms, Stages & Best Exercises
Is your shoulder becoming increasingly painful and stiff? Are simple activities like combing your hair, fastening your bra, reaching for a shelf, or putting on a shirt becoming difficult?
If yes, you may be suffering from Frozen Shoulder, medically known as Adhesive Capsulitis.
Frozen shoulder is a common condition in which the shoulder joint becomes painful and progressively loses its range of motion. Fortunately, with proper treatment and rehabilitation, most patients recover significant function.
What Is Frozen Shoulder?
The shoulder is surrounded by a flexible capsule that allows it to move freely in multiple directions.
In frozen shoulder, this capsule becomes inflamed, thickened, and tight, leading to:
- Pain
- Stiffness
- Progressive loss of shoulder movement
Unlike a muscle strain, frozen shoulder affects the joint capsule itself, making even passive movement painful and restricted.
Who Is Most Commonly Affected?
Frozen shoulder most commonly occurs in:
| Risk Factor | Higher Risk |
|---|---|
| Age | 40–60 years |
| Diabetes | Yes |
| Thyroid disorders | Yes |
| Women | Slightly more common |
| Previous shoulder injury | Yes |
| Shoulder surgery | Yes |
| Long-term shoulder immobilization | Yes |
People with diabetes have a significantly higher risk of developing frozen shoulder compared to the general population.
Why Does Frozen Shoulder Develop?
In many patients, no definite cause is identified.
However, several conditions increase the likelihood of developing the disease.
Common causes include:
- Diabetes mellitus
- Thyroid disorders
- Shoulder injury
- Rotator cuff problems
- Stroke
- Heart surgery
- Shoulder fracture
- Prolonged use of a sling
- Previous shoulder surgery
Clinical Note
Frozen shoulder may develop gradually without any obvious injury. Many patients simply notice increasing pain followed by progressive stiffness over several months.
The Three Stages of Frozen Shoulder
One of the unique features of frozen shoulder is that it usually progresses through three distinct stages.
Stage 1 – Freezing Stage
Duration: Approximately 2–9 months
Typical symptoms:
- Increasing shoulder pain
- Pain during movement
- Difficulty sleeping on the affected side
- Gradually decreasing shoulder movement
Pain is usually the dominant complaint during this stage.
Stage 2 – Frozen Stage
Duration: Approximately 4–12 months
During this stage:
- Pain may begin to improve
- Shoulder becomes very stiff
- Daily activities become difficult
- Lifting the arm becomes challenging
Although pain often decreases, stiffness becomes more noticeable.
Stage 3 – Thawing Stage
Duration: 6–24 months
Recovery gradually occurs.
Patients usually notice:
- Improving shoulder movement
- Less stiffness
- Better daily function
- Reduced discomfort
Recovery is often slow but steady.

Common Symptoms
Patients may experience:
- Shoulder pain
- Difficulty lifting the arm
- Pain while sleeping
- Difficulty reaching overhead
- Trouble fastening clothes
- Difficulty combing hair
- Pain while reaching behind the back
- Reduced shoulder movement
Everyday Activities That Become Difficult
Many patients first notice problems during routine tasks.
Examples include:
| Activity | Difficulty |
|---|---|
| Combing hair | Common |
| Wearing a shirt | Common |
| Fastening bra or belt | Common |
| Reaching overhead | Common |
| Driving | Sometimes |
| Sleeping on affected side | Very Common |
How Is Frozen Shoulder Diagnosed?
Diagnosis is usually based on:
Medical History
Your doctor will ask about:
- Duration of symptoms
- Previous injuries
- Diabetes
- Thyroid disease
- Previous shoulder surgery
Physical Examination
Your orthopaedic surgeon evaluates:
- Active shoulder movement
- Passive shoulder movement
- Strength
- Pain location
- Joint stiffness
A characteristic feature is that both active and passive movements are restricted.
Imaging
Imaging helps exclude other shoulder conditions.
| Investigation | Purpose |
|---|---|
| X-ray | Rule out arthritis or fractures |
| MRI | Evaluate rotator cuff and other soft tissues if needed |
| Ultrasound | Selected patients |
Treatment Options
Treatment depends on the stage of the disease and the severity of symptoms.
Pain Relief
Initial treatment may include:
- Activity modification
- Ice application
- Heat therapy
- Anti-inflammatory medications
- Gentle stretching
Physiotherapy
Physiotherapy is one of the most important components of treatment.
Goals include:
- Reducing stiffness
- Improving mobility
- Restoring shoulder function
- Preventing further loss of movement
Consistency is more important than intensity.
Corticosteroid Injection
For selected patients with significant pain, a corticosteroid injection may help reduce inflammation and improve participation in physiotherapy.
The decision should be individualized after consultation with an orthopaedic specialist.
Surgical Treatment
Most patients improve without surgery.
However, if severe stiffness persists despite prolonged conservative treatment, procedures such as:
- Manipulation under anaesthesia (selected cases)
- Arthroscopic capsular release
may be considered.
Home Exercises
Exercises should be performed only after evaluation by a healthcare professional.
1. Pendulum Exercise
- Lean forward slightly.
- Let the affected arm hang freely.
- Move the arm gently in small circles.
- Continue for one to two minutes.
2. Wall Climbing Exercise
- Face a wall.
- Walk your fingers upward as high as comfortable.
- Hold briefly.
- Slowly return.
Repeat several times.
3. Towel Stretch
Hold a towel behind your back with both hands.
Use the healthy arm to gently pull the affected arm upward.
Stretch gently without forcing the movement.
4. Cross-Body Stretch
Bring the affected arm across your chest.
Use the opposite hand to support the stretch.
Hold for 20–30 seconds.
Exercise Tip
Gentle stretching performed regularly is generally more effective than occasional aggressive stretching, which may worsen pain.
Common Mistakes
Avoid these common errors during recovery:
- Ignoring persistent shoulder pain
- Keeping the arm completely immobile
- Performing painful forceful exercises
- Stopping physiotherapy too early
- Self-medicating with repeated painkillers without medical advice
Frequently Asked Questions
Is frozen shoulder permanent?
No.
Most patients gradually recover substantial shoulder movement, although the recovery process may take several months.
Can frozen shoulder heal without surgery?
Yes.
Most patients improve with medications, physiotherapy, stretching exercises, and time.
Is exercise painful?
Some mild discomfort during stretching is expected, but exercises should not cause severe or prolonged pain.
Your physiotherapist will guide you regarding appropriate intensity.
Can frozen shoulder come back?
Recurrence in the same shoulder is uncommon, but some individuals may later develop frozen shoulder in the opposite shoulder.
Is frozen shoulder the same as a rotator cuff tear?
No.
Frozen shoulder primarily affects the shoulder capsule, whereas a rotator cuff tear involves the tendons surrounding the shoulder joint. Although symptoms may overlap, the treatment approach differs.
Recovery Timeline
| Stage | Approximate Duration |
|---|---|
| Freezing | 2–9 months |
| Frozen | 4–12 months |
| Thawing | 6–24 months |
Recovery varies from person to person and depends on factors such as diabetes, adherence to physiotherapy, and overall shoulder health.
Key Takeaways
Frozen shoulder is a treatable condition, but recovery requires patience, consistency, and appropriate rehabilitation.
- Early diagnosis can prevent unnecessary disability.
- Physiotherapy plays a central role in treatment.
- Most patients recover without surgery.
- Regular stretching exercises are essential for improving shoulder movement.
- People with diabetes should seek medical evaluation early if shoulder stiffness develops.
