What happens if shoulder impingement is not treated?

Shoulder impingement occurs when tissues around the shoulder become irritated during certain movements, often when the arm is lifted or reaches overhead. Continuing painful activity can keep the area sensitive and encourage guarded movement. Over time, reduced use may affect shoulder strength and range. Pain when lifting the arm and shoulder pain can also arise from a rotator cuff problem, frozen shoulder, arthritis or another condition, so the label should be confirmed by examination.

Arrange an assessment if symptoms persist, disturb sleep or interfere with work, dressing or sport. A clinician may examine movement and strength and recommend a graded rehabilitation plan. Physiotherapy can address shoulder control, posture, strength and the loads that provoke symptoms. A Cortisone Injection may be discussed for selected short-term symptom relief. Subacromial Decompression is reserved for particular cases after assessment and appropriate non-surgical care; it is not automatically needed for every painful shoulder.

Seek prompt care after a fall or sudden injury, or if the shoulder becomes visibly deformed, hot, red or swollen. Obtain urgent assessment for sudden inability to lift the arm, marked new weakness, chest pain, breathlessness, fever or unexplained severe pain. Persistent night pain or steadily worsening movement also warrants review.

Which shoulder structures are involved? What movements should I modify? How long should I try rehabilitation before reviewing progress? Would an injection help my goals, and what findings would make surgery reasonable?
