Understanding frozen shoulder

When reaching becomes difficult

Reaching a shelf, combing your hair or fastening clothing can become unexpectedly difficult when a shoulder is painful and stiff. Frozen shoulder, also called adhesive capsulitis, is one possible explanation. The joint capsule becomes thickened and tight, restricting movement. Other conditions can also cause shoulder pain, so the label should follow an assessment. 1

How can it develop?

Frozen shoulder is often described in three overlapping phases: pain increases while movement reduces, stiffness remains prominent, and movement gradually returns. The pace varies. It is associated with conditions including diabetes and can also develop after a shoulder has been kept still following an injury or operation. It is not simply a matter of having a weak shoulder. 1

Pain may disturb sleep, and everyday activities can become uncomfortable. Recovery can take months or longer; a difficult week does not necessarily tell you how the shoulder will behave over the whole course of recovery. 2

What will the doctor check?

The examination compares movement you make yourself with movement the clinician gently assists. Both may be restricted in frozen shoulder. Depending on the findings, tests may help rule out another problem, such as arthritis or a tendon injury. An MRI is not automatically required to diagnose every stiff shoulder. 1

Tell the doctor when the problem began, whether an injury came first and how it affects sleep or daily tasks. Mention diabetes and any previous shoulder treatment.

What can treatment involve?

The plan usually combines pain management with gradually restoring movement. Depending on your symptoms, a clinician may discuss medicines, an injection or physiotherapy. The appropriate combination depends on how painful and restricted the shoulder is. 2

Gentle movement is helpful, but avoid forcing the shoulder or starting strenuous, improvised exercises. A physiotherapist can advise which movements to practise and how to progress them. Persistent pain or stiffness that limits use of the arm deserves a consultation. 2

Questions worth asking

• What makes frozen shoulder more likely than another diagnosis in my case?
• Which activities can I continue comfortably?
• What should I expect from the first part of treatment?
• When should we reassess the plan?

These questions help turn a broad treatment discussion into practical next steps for your routine.
