How long does physiotherapy take to work for frozen shoulder?

Frozen shoulder can make reaching, dressing and sleeping uncomfortable while the joint becomes stiff. Early rehabilitation often prioritises pain control and gentle movement; later work may add stretching, joint mobility and strengthening as tolerance improves. Progress is better judged by tasks such as reaching a shelf or putting on a shirt than by forcing the arm through a painful range. A shoulder can remain irritable if exercises are advanced too quickly.

Perform the prescribed movements regularly but gently, and avoid aggressive stretching that causes a lasting flare. Use the therapist’s guidance on heat, posture, sleep position and activity modification. Mention diabetes, thyroid disease, a recent shoulder injury or a sudden change in pain because these details may affect assessment and planning. Explore [Frozen Shoulder](/conditions/frozen-shoulder/) and [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/).

Seek review if pain is escalating, movement is worsening despite following the plan, or new numbness or weakness develops in the arm or hand. Urgent assessment is needed after a significant injury, with a visibly deformed shoulder, severe swelling, fever, chest pain, or sudden breathing difficulty. A clinician can check whether stiffness is still consistent with frozen shoulder or whether another issue is present.

Which phase of frozen shoulder am I in? What amount of discomfort during stretching is acceptable? Which movements should I practise daily? When would another treatment or a reassessment be appropriate? How can I protect sleep while keeping the shoulder moving?
