An individual must have sustained an injury to the muscles that stretch between the bones of their shoulder for it to be impingement syndrome. Sometimes the cause of impingement syndrome is rotator cuff tendinitis, and sometimes it is a different type of muscle injury. The majority of patients with this type of injury can recover by following an exercise plan, stretching the injured area, using medication to manage pain and heal the muscle, and avoiding engaging in repeated motions over the head. Shoulder bursitis is another condition that may be linked to impingement syndrome. This occurs when the bursae that cushion the shoulder joint become inflamed, leading to pain and irritation.
