Understanding Frozen Shoulder

Frozen shoulder, also known as adhesive capsulitis, is a painful condition characterised by progressive stiffness and loss of movement in the shoulder joint. It typically develops gradually and can cause significant disruption to sleep, work, and everyday activities such as dressing and reaching overhead. Frozen shoulder most commonly affects adults between 40 and 60 years of age and is more frequent in people with diabetes or thyroid disease, though it can also occur without an obvious trigger. The condition usually follows a prolonged course, often lasting many months or longer. While frozen shoulder often improves over time, appropriate management can reduce pain, improve function, and shorten the duration of symptoms. Many patients seek private care because of severe pain, sleep disturbance, or limited progress with initial NHS management.

What is frozen shoulder?

Frozen shoulder is a condition involving inflammation and thickening of the joint capsule surrounding the shoulder, leading to progressive restriction of movement. It is classically described as progressing through stages: an early painful phase, a stiff “frozen” phase, and a later recovery or “thawing” phase. The underlying cause is not fully understood, but the process results in capsular tightening and reduced joint volume. This explains why both active and passive shoulder movements become restricted, distinguishing frozen shoulder from other causes of shoulder pain.

Symptoms and functional impact?

Common symptoms include persistent shoulder pain, often worse at night, and increasing stiffness affecting all directions of movement. Patients may struggle with everyday tasks such as dressing, fastening bras, washing hair, or reaching behind the back. Sleep disturbance is common and can be severe. As stiffness progresses, pain may lessen but functional limitation often becomes more pronounced. The impact on work and quality of life can be substantial, particularly for patients with physically demanding jobs or caring responsibilities.

Assessment and diagnosis

Diagnosis is primarily clinical, based on a characteristic history and examination demonstrating global restriction of shoulder movement, particularly external rotation. Imaging is usually normal in early disease and is mainly used to exclude alternative diagnoses such as rotator cuff pathology or arthritis. X-rays may be performed to rule out structural joint disease. Accurate staging of frozen shoulder is important, as it influences treatment choice and expected response.

Treatment options

Treatment options
Management depends on the stage of frozen shoulder and the severity of symptoms. In the early painful phase, treatment focuses on pain control and maintaining gentle movement. Image-guided intra-articular corticosteroid injections have good evidence for reducing pain and improving function, particularly when used early in the disease course.
For patients with persistent stiffness or limited improvement after initial treatment, hydrodistension (capsular distension) may be considered. This involves injecting fluid into the shoulder joint under imaging guidance to stretch the tightened capsule.


Physiotherapy may be helpful at certain stages to support recovery, but overly aggressive stretching can worsen symptoms in the painful phase. Surgical interventions are reserved for a small number of patients with severe, persistent stiffness despite appropriate non-operative care.

What is frozen shoulder?
Frozen shoulder, also known as adhesive capsulitis, is a condition characterised by inflammation and thickening of the shoulder joint capsule, leading to pain and progressive stiffness.
No. Frozen shoulder affects the soft tissues surrounding the joint rather than the joint surfaces themselves and is a different condition from osteoarthritis.
Not usually. Frozen shoulder is primarily diagnosed clinically. Imaging is mainly used to exclude other causes of shoulder pain or stiffness rather than to confirm the diagnosis.
Yes. We are happy to review previous X-rays, ultrasound scans, MRI scans, and radiology reports from NHS or private providers.
Yes. If imaging is clinically appropriate, we can arrange X-rays, ultrasound, or MRI scans as part of your assessment and explain how the results will inform management.
Plain X-rays are often used to rule out arthritis or other structural problems. MRI or ultrasound may be used if rotator cuff pathology or other conditions are suspected.
Not always. Imaging findings in frozen shoulder are often subtle or absent, particularly early on, and do not reliably reflect symptom severity.
No. Many patients attend after physiotherapy has not improved symptoms or when pain is severe. We will advise if further physiotherapy is likely to be helpful and at what stage.
Treatment options depend on the stage of the condition and symptom severity. These may include pain management advice, image-guided intra-articular corticosteroid injection,hydrodistension and guidance on onward care.
Steroid injections are most effective in the early painful phase of frozen shoulder, where they can reduce pain and improve movement.
No. Injections aim to reduce pain and improve function but do not immediately resolve the condition, which often follows a prolonged course.
A steroid injection involves placing corticosteroid medication into the shoulder joint to reduce inflammation and pain. It is most effective in the early painful phase of frozen shoulder.

Hydrodistension involves injecting a larger volume of fluid into the joint to stretch the tightened capsule. It is more commonly considered later in the condition, particularly where stiffness remains a dominant problem. The two treatments address different aspects of frozen shoulder and are used at different stages rather than as alternatives for everyone.
Neither treatment is universally “better”. The most appropriate option depends on the stage of the condition, symptom pattern, and response to previous treatment. We will advise which approach is more suitable for your individual situation.
In some cases, yes. A steroid injection may be used earlier in the condition, with hydrodistension considered later if stiffness persists. This is assessed on an individual basis.
The condition commonly lasts many months and sometimes longer. Appropriate treatment can reduce pain and may shorten the overall course in some patients.
In most cases, yes. The majority of patients improve without surgery. Operative treatments are reserved for selected cases with persistent severe stiffness.
Delayed or inappropriate management can prolong symptoms and stiffness, but most patients do eventually improve. Early assessment can help guide appropriate treatment and expectations.
Gentle movement is usually encouraged. Aggressive stretching during the painful phase can worsen symptoms, and advice should be stage-appropriate.
