Gradual pain
A dull or aching pain may develop without a major injury and can extend into the upper arm.
HISTORYRECOGNISING THE CLINICAL PATTERN
Symptoms and diagnosis
Frozen shoulder is usually identified from the story of how symptoms developed and a physical examination showing a characteristic restriction of both self-directed and assisted shoulder movement.
ONSETUsually gradual rather than one sudden event
KEY FINDINGActive and passive movement are both restricted
IMAGINGOften used to exclude another cause—not prove the diagnosis alone
THE WHOLE PICTURE
No single symptom confirms frozen shoulder. Clinicians look for a recognisable combination of pain, stiffness, movement loss and time.
The diagnosis is primarily clinical.
A clinician considers how symptoms started, whether they are changing, which movements are restricted and how the shoulder behaves when it is moved with assistance. Age, injury or surgery, diabetes, thyroid conditions and other health factors may also be relevant.
The pattern can look different in a highly painful early phase than in a later stiffness-dominant phase. Guarding caused by pain can also make movement assessment more difficult.
Frozen shoulder is not simply any painful shoulder with limited movement. Other conditions may resemble it, coexist with it, or require different investigation and care.
COMMON FEATURES
What may form part of the pattern?
Individual experiences vary, but these features commonly prompt consideration of frozen shoulder.
Night disturbance
Pain may be worse at night or when lying on the affected side, particularly during the painful phase.
PAIN PATTERNProgressive stiffness
Reaching overhead, behind the back or out to the side becomes increasingly difficult.
MOVEMENTRestricted assistance
The joint remains limited even when the arm is gently moved by someone else.
PASSIVE RANGELimited outward rotation
External rotation with the elbow near the side is commonly and disproportionately restricted.
KEY DIRECTIONDaily-life impact
Dressing, washing, driving, work, sleep and comfortable arm use may all be affected.
FUNCTIONTHE ASSESSMENT
What happens during an examination?
Assessment should be respectful and adapted to pain. It is not necessary to force the shoulder to establish that movement is restricted.
Your history
How and when symptoms began; pain behaviour; sleep; work and daily limitations; injury, surgery and relevant health conditions.
Observation
How naturally the arm is used, whether the trunk or shoulder blade compensates, and whether swelling, deformity or another concern is visible.
Active movement
You move the arm yourself in several directions so the clinician can assess available range, pain and movement strategy.
Passive movement
The clinician gently moves the relaxed arm. In frozen shoulder, this assisted range is also restricted—not only the movement you produce yourself.
Other tests
Strength, neck, elbow, neurological or other shoulder tests may be used selectively to examine alternative explanations.
ACTIVE AND PASSIVE RANGE
Why does the difference matter?
This distinction helps clinicians decide whether movement is limited mainly by the person’s ability to produce it or by restriction within the joint itself.
You move your own arm
Pain, weakness, confidence, coordination and joint restriction can all influence how far the arm moves.
The relaxed arm is moved for you
Frozen shoulder typically restricts this assisted range as well, particularly external rotation.
Restricted passive movement is important, but it is interpreted alongside the complete history and examination—not used as a stand-alone home test.
SCANS AND TESTS
Do you need imaging?
Many people do not need advanced imaging to diagnose a typical frozen shoulder.
Looking at bone and joint space
A frozen shoulder may not be visible on an X-ray. The test can help identify or exclude arthritis, fracture and other bony causes of stiffness.
Looking at soft tissues
These tests are not normally required to prove frozen shoulder, but may help when symptoms are atypical or another soft-tissue condition is suspected.
Checking broader health
Blood tests do not diagnose frozen shoulder directly. They may be considered when diabetes, thyroid disease, infection or another systemic condition is relevant.
OTHER POSSIBILITIES
What else can cause shoulder pain or stiffness?
This is why diagnosis should not be based on an online symptom list alone.
Shoulder osteoarthritis
Can produce pain and passive stiffness; X-rays may help distinguish bony joint change.
Rotator-cuff-related pain or tear
May limit active movement through pain or weakness, while assisted movement can be less restricted.
Calcific tendinopathy
Can cause severe shoulder pain and restricted use, sometimes with a more acute presentation.
Neck or nerve-related symptoms
Neck pain, altered sensation, pins and needles or neurological weakness may point beyond the shoulder joint.
Injury, fracture or dislocation
A clear traumatic event, deformity, bruising or sudden inability to use the arm requires appropriate assessment.
Inflammatory or systemic illness
Multiple painful joints, fever, feeling unwell, unexplained weight loss or other broader symptoms need medical attention.
PREPARING FOR AN APPOINTMENT
Information that helps your clinician.
You do not need perfect answers. A simple account of the problem can make the assessment more focused.
01
When did symptoms begin, and was there an injury, illness or operation?
02
Where is the pain, and what happens at night or with sudden movement?
03
Which daily tasks and movement directions have become difficult?
04
How have pain and stiffness changed over weeks or months?
05
What treatments have you tried, and what happened afterwards?
06
What relevant conditions, medicines and personal recovery goals should be considered?
WHEN TO SEEK HELP
Some symptoms require prompt assessment.
Arrange professional assessment for persistent pain and stiffness, substantial loss of movement, new weakness or numbness, or symptoms that do not fit the expected pattern.
Seek urgent medical help after serious injury, or for chest pain, breathlessness, sudden weakness, deformity, or a hot red swollen joint with fever or feeling unwell.
