Shoulder pain is a common complaint that can range from a mild ache to severe discomfort. It can be caused by a variety of factors, including overuse, trauma, or an underlying medical condition. Common symptoms of shoulder pain include a dull ache, tenderness, or a sharp, stabbing sensation. Diagnosis typically involves a physical examination, imaging tests, and in some cases, lab tests to rule out underlying causes. Treatment typically involves rest, physical therapy, medications, and in some cases, surgery.
