Frozen shoulder, also called adhesive capsulitis, causes pain and progressive stiffness in the shoulder joint. It commonly develops over months and can make reaching overhead, dressing, sleeping and everyday movement difficult. Recovery is often gradual, but appropriate treatment and guided mobility exercises can help restore function.
What is frozen shoulder?
Frozen shoulder is a condition in which the capsule surrounding the shoulder joint becomes painful, thickened and stiff. The capsule is a flexible layer of tissue that helps stabilize the joint while allowing movement.
As the capsule tightens, shoulder motion becomes restricted. People often have difficulty reaching overhead, reaching behind the back, putting on a coat, fastening clothing or sleeping on the affected side. 1 2
Important distinction: Frozen shoulder affects both active movement, when you move the arm yourself, and passive movement, when a clinician moves the arm for you. This helps distinguish it from some rotator cuff problems.
Frozen shoulder symptoms and stages
Frozen shoulder usually develops gradually. The stages can overlap, and not everyone experiences them in exactly the same way.
Common symptoms
- Deep, aching shoulder pain
- Pain that is worse at night
- Difficulty reaching overhead
- Difficulty reaching behind the back
- Reduced ability to rotate the arm outward
- Progressive stiffness that affects daily activities
Frozen shoulder or another shoulder problem?
What causes frozen shoulder?
Frozen shoulder may develop without a clear trigger. It can also occur after an injury, surgery or period of reduced shoulder movement.
Factors associated with a higher risk include:
- Age between approximately 40 and 60
- Diabetes
- Thyroid disorders
- Parkinson disease
- Stroke
- Prolonged shoulder immobilization
- Recovery after shoulder surgery or injury
Women are diagnosed more often than men, although frozen shoulder can affect anyone. 1 3
Diagnosis: A clinician usually diagnoses frozen shoulder from the history and physical examination. X-rays or other imaging may be used to rule out arthritis, fracture or another cause of pain.
Frozen shoulder treatment
Treatment aims to control pain, maintain safe movement and gradually restore shoulder function. The best approach depends on the stage, symptom severity and overall health.
| Treatment | How it may help | Important considerations |
|---|---|---|
| Activity modification | Reduces repeated movements that sharply aggravate the shoulder. | Avoid complete immobilization unless specifically instructed. |
| Heat or cold | Heat may improve comfort before movement, while cold may help after an aggravating activity. | Protect the skin and avoid prolonged exposure. |
| Pain medication | May reduce discomfort enough to support sleep and exercise. | Use only when appropriate for your health and according to a clinician or pharmacist. |
| Physical therapy | Provides individualized mobility, strengthening and activity guidance. | Aggressive stretching may worsen pain, especially early on. |
| Corticosteroid injection | May reduce pain and improve movement, particularly during the painful stage. | Benefits and risks should be discussed with a qualified clinician. |
| Hydrodilatation | Uses fluid injected into the joint capsule to stretch it. | Availability and benefit vary. |
| Manipulation or surgery | May be considered when severe restriction persists despite conservative care. | These options carry risks and are not first-line treatments. |
Before starting shoulder exercises
Use a gentle range. Frozen shoulder exercises should create mild tension, not sharp pain or forceful stretching.
- Move slowly and avoid bouncing.
- Do not force the shoulder through severe pain.
- Stop if pain remains noticeably worse afterward.
- Begin with fewer repetitions and progress gradually.
- Seek professional guidance after surgery, fracture or a significant shoulder injury.
Frozen shoulder exercises and stretches
These movements may help maintain or gradually improve shoulder mobility. Exercise selection and intensity should match the stage of the condition.
Pendulum exercise
Lean forward with one hand supported on a table. Let the affected arm hang comfortably, then make small circles using gentle body movement.
Assisted shoulder flexion
Lie on your back and hold a cane or wand with both hands. Use the unaffected arm to help raise the affected arm overhead within a comfortable range.
Assisted external rotation
Keep both elbows close to the body and bent to approximately 90 degrees. Hold a cane and use the unaffected arm to gently move the affected forearm outward.
Table slide
Sit facing a table with the affected arm resting on a towel. Slide the hand forward as the body gently leans toward the table.
Cross-body stretch
Use the unaffected arm to guide the affected arm gently across the chest. Keep the shoulder down and avoid shrugging.
Wall walk
Face a wall and use the fingers of the affected arm to slowly walk upward. Stop before the shoulder becomes sharply painful.
Scapular setting
Sit or stand tall. Gently draw the shoulder blades back and slightly down without arching the lower back.
Doorway chest stretch
Place the forearm against a doorway at a comfortable height. Step forward gently until a mild stretch is felt across the chest.
How long does frozen shoulder last?
Frozen shoulder often improves gradually, but recovery can take many months. Some people recover within approximately one to two years, while others experience symptoms for longer.
Recovery time varies according to the stage, severity, underlying health conditions and treatment response. Early assessment can help rule out other causes of shoulder pain and guide a suitable plan.
When should you seek medical care?
Arrange an evaluation if shoulder pain and stiffness are worsening, interfere with sleep, or significantly limit normal movement.
Seek prompt medical attention for:
- Shoulder pain after a fall or major injury
- Visible deformity or inability to move the arm
- Sudden severe weakness
- Numbness or tingling that extends into the hand
- Redness, warmth, fever or signs of infection
- Chest pain, shortness of breath or pain radiating into the jaw
Frozen shoulder FAQ
Can frozen shoulder go away on its own?
Frozen shoulder can improve over time, but recovery may be slow. Treatment may help manage pain, preserve movement and support a safer return to normal activity.
Should I stretch a frozen shoulder every day?
Gentle daily movement may be helpful, but the correct amount depends on the stage and symptom response. Aggressive stretching can aggravate the painful stage.
Is heat or ice better for frozen shoulder?
Heat may improve comfort before movement, while ice may help after an aggravating activity. Use whichever provides relief, protect the skin and avoid prolonged exposure.
Can diabetes make frozen shoulder more likely?
Yes. Frozen shoulder is more common among people with diabetes, and symptoms may be more persistent.
Can frozen shoulder return?
It may recur, although recurrence in the same shoulder is uncommon. The opposite shoulder can be affected in some people.
