What should you know about subacromial subdeltoid bursitis?

The subacromial and subdeltoid bursa helps the rotator cuff and surrounding tissues move smoothly beneath the shoulder roof. Repeated overhead activity, a sudden increase in use or irritation from nearby tissues can inflame it.

Pain may be felt at the outer shoulder or upper arm and may increase when reaching overhead, dressing or lying on the affected side. Stiffness and weakness can occur because pain limits movement. A clinician may compare shoulder strength and motion and use imaging when another cause needs checking.

Shoulder swelling can reflect several problems. Local swelling, warmth or marked tenderness is worth reporting rather than assuming it is simple bursitis.

Reduce painful overhead work temporarily, but keep gentle shoulder movement within a comfortable range. Support the arm during rest and use a wrapped cold pack for short periods if that feels helpful. Medication advice should account for your other conditions and medicines.

A clinician may recommend anti-inflammatory medication when suitable. If pain remains limiting, a cortisone injection can be discussed after diagnosis. Joint aspiration is reserved for situations where fluid needs to be removed or tested; it is not needed for every shoulder complaint.

Get prompt care for fever, a hot or very red shoulder, rapidly increasing swelling, severe pain after an injury, new major weakness or inability to move the arm. Arrange an appointment for persistent night pain, recurring symptoms or difficulty with work and daily tasks.

Ask: Is the bursa the main source of pain? Could a tendon, joint or neck problem be involved? Which movements should I modify? Would medication, an injection or fluid testing help, and what rehabilitation should follow?
