Shoulder impingement syndrome
Shoulder impingement is a pinching of soft tissues in the shoulder. It happens when the tissues press against part of the shoulder blade. It’s common in people who do a lot of overhead arm motions, like baseball players, swimmers and construction workers.
Shoulder impingement causes pain, swelling, reduced range of motion and shoulder weakness. Treatment includes rest, medications, cortisone shots and physical therapy. In severe cases, surgery may be needed.
