What should you know about a muscle contusion in the shoulder?

A blow can damage small blood vessels and muscle fibres beneath the skin without breaking the skin. The area may look red, purple, or swollen later, and pressing on it or lifting the arm can hurt. A contusion is different from a cut, though a significant impact can occur alongside a shoulder joint or bone injury. Pain should gradually become easier as the tissues settle; persistent weakness, a changed shoulder shape, or inability to use the arm needs assessment.

Protect the shoulder from another impact and reduce activities that increase pain. Cold therapy wrapped in cloth may help during the early phase; avoid placing ice directly on skin. Keep the elbow, wrist, and hand moving gently, and add comfortable shoulder motion as pain allows. Do not force stretches or deep massage over a fresh bruise. A physiotherapist can guide a gradual return to work, exercise, and overhead movement. Read about [Hot and Cold Therapy](/treatments/physiotherapy-and-rehabilitation/hot-and-cold-therapy/) and [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/).

Seek urgent care after a major injury if the arm is numb, cold, pale, visibly deformed, or impossible to move, or if pain and swelling are rapidly increasing. Arrange a clinical assessment when bruising is extensive, movement remains very limited, or symptoms are not settling. A clinician may examine the shoulder and decide whether imaging is needed.
