Frozen Shoulder — What It Is, What to Expect and How Osteopathy Can Help

Frozen shoulder is one of those conditions that tends to arrive uninvited, progresses on its own timeline and — frustratingly — doesn’t always respond to the usual approaches that work for other shoulder problems.

If you’ve been told you have frozen shoulder, or if you’re experiencing a gradual onset of shoulder pain and stiffness that’s beginning to limit your movement, this article is for you. I want to explain what frozen shoulder actually is, what causes it, what the three stages look like in practice and how osteopathy can support you through each phase of recovery.

What Is Frozen Shoulder?

Frozen shoulder — medically known as adhesive capsulitis — is a condition in which the joint capsule of the shoulder becomes thickened, inflamed and contracted. This causes pain and a progressive restriction of movement in all directions — not just in one plane, which is what distinguishes it from most other shoulder conditions.

It is most common between the ages of 40 and 60 and affects women slightly more often than men. In most cases it develops without any obvious cause, though certain risk factors are well established.

What Causes Frozen Shoulder?

The exact mechanism behind frozen shoulder is not fully understood, but known risk factors include:

• Diabetes — people with diabetes have a significantly higher risk of developing frozen shoulder and may experience a more prolonged course
• Thyroid disorders — both hypothyroidism and hyperthyroidism have been associated with increased risk
• Cardiovascular disease
• Previous shoulder injury or surgery — any period of shoulder immobilisation can trigger the process
• Age — most common between 40 and 60
• Being female — slightly more prevalent in women than men
• Dupuytren’s contracture — a connective tissue condition affecting the hand, associated with increased frozen shoulder risk

In many cases, none of these risk factors are present and frozen shoulder develops without any clear precipitating cause — which can make it feel particularly baffling for patients.

The Three Stages of Frozen Shoulder

Understanding the stages is genuinely helpful — both for managing expectations and for understanding why treatment looks different at different points.

Stage 1 — The Freezing Stage (2–9 months)

This is the most painful phase. Symptoms typically begin gradually — a dull ache in the shoulder that becomes increasingly uncomfortable, often worse at night. Movement begins to become restricted, and patients frequently report difficulty sleeping on the affected side.

The freezing stage can be deeply frustrating because the pain is often significant while the stiffness is still developing. People sometimes assume the problem is a rotator cuff injury at this stage, which is why accurate diagnosis matters.

Stage 2 — The Frozen Stage (4–12 months)

In the frozen stage, pain may ease slightly — but stiffness reaches its peak. Movement in all directions becomes significantly restricted. Everyday tasks become surprisingly difficult: reaching into a cupboard, putting on a coat, fastening a seatbelt or reaching behind the back.

This stage requires the most adaptation in daily life and is often when patients seek osteopathic assessment.

Stage 3 — The Thawing Stage (6 months to 2 years)

Movement gradually returns as the capsule loosens. This process is usually slow and not always linear — there can be periods of improvement followed by apparent plateaus. Most people achieve a good or full recovery over time, though the total duration from onset to resolution typically ranges from 1 to 3 years.

Myths & Misconceptions

• “There’s no point seeking treatment — it resolves on its own” — while frozen shoulder does eventually resolve in most cases, treatment can significantly reduce pain, speed recovery and improve function during each stage. Waiting it out without support is rarely the most effective approach
• “Frozen shoulder and rotator cuff injury are the same thing” — they are distinct conditions. Rotator cuff problems typically restrict movement in specific directions; frozen shoulder restricts movement in all directions and has a characteristic capsular pattern
• “I should push through the stiffness aggressively” — aggressive stretching in the early stages can worsen pain and irritate an already inflamed capsule. Gentle, progressive movement within comfortable limits is more appropriate
• “Complete rest is needed” — while protecting the shoulder from aggravating activities is sensible, complete immobilisation can worsen stiffness
• “Surgery is always needed” — the majority of people with frozen shoulder recover without surgical intervention. Surgery is generally only considered for persistent cases that have failed to respond to conservative management over a prolonged period
• “It will never fully recover” — most people achieve a good or full recovery over time. Patience is required, but the prognosis is generally positive

How Is Frozen Shoulder Diagnosed?

Diagnosis is primarily clinical — based on your history and a physical examination assessing the characteristic pattern of restricted movement. Imaging such as MRI or ultrasound may occasionally be recommended to exclude other shoulder pathology, but is not always necessary.

The key clinical feature that distinguishes frozen shoulder from other shoulder conditions is restriction of movement in all planes — particularly external rotation — rather than restriction in one specific direction.

How May Osteopathy Help?

Osteopathic management of frozen shoulder is tailored to the stage of the condition. What’s appropriate in the freezing stage is different from what’s appropriate in the thawing stage — and getting this right matters.

During the freezing stage:

• Gentle soft tissue techniques to reduce surrounding muscle tension and ease pain
• Myofascial release to address fascial restrictions around the shoulder and upper back
• Pain management advice and education about the condition and its stages
• Guidance on sleep positions and activities to avoid

During the frozen stage:

• Gentle joint mobilisation within comfortable limits to maintain what movement is available
• Muscle energy techniques to encourage gentle capsular lengthening
• Exercise rehabilitation — gentle, appropriate exercises to maintain movement and prevent further deconditioning
• Upper back and neck treatment where stiffness in these areas is contributing to shoulder restriction

During the thawing stage:

• Progressive mobilisation and rehabilitation as movement returns
• Strengthening exercises to restore rotator cuff and shoulder blade function
• Guidance on returning to full activity

Throughout all stages, education and realistic expectation-setting are central to treatment. Understanding what’s happening and why — and knowing that recovery, though slow, is achievable — makes a meaningful difference to how people experience the condition.

Evidence at a Glance

Current clinical evidence suggests that:

• Frozen shoulder is a self-limiting condition in most cases — meaning it does eventually resolve — but the timeline is highly variable
• Corticosteroid injections can provide meaningful short-term pain relief, particularly in the freezing stage, and may be worth discussing with your GP
• Manual therapy and exercise rehabilitation are supported by evidence as effective components of conservative management
• Distension arthrography (hydrodilatation) — a procedure that stretches the shoulder capsule using injected fluid — can be effective for some patients in the frozen stage and is worth discussing with a specialist if progress is slow
• Surgery (manipulation under anaesthetic or arthroscopic capsular release) is effective for persistent cases but is generally reserved for those who have not responded to conservative management

Frequently Asked Questions

How long does frozen shoulder last?
Total duration from onset to resolution typically ranges from 1 to 3 years, though individual variation is significant. Treatment can reduce pain and support recovery during this period.

Is frozen shoulder the same as a rotator cuff tear?
No. They are distinct conditions. A thorough assessment will help identify which is most likely contributing to your symptoms. Read more about rotator cuff tears →

Can I still exercise with frozen shoulder?
Yes — gentle, appropriate exercise is generally encouraged. The type and volume of exercise should be guided by your stage of the condition and your current comfort level.

Does frozen shoulder affect both shoulders?
In some people, yes — frozen shoulder can develop in the other shoulder, sometimes years later. This is more common in people with diabetes.

Will I need surgery?
Most people recover without surgery. Surgery is considered for persistent cases that haven’t responded to conservative management over a prolonged period.

Can stress make it worse?
Yes. Stress increases muscle tension and pain sensitivity, which can amplify symptoms. Read more about whether stress can cause pain →
