Shoulder pain may be the result of damaged muscles, tendons or ligaments or a bone fracture. If the cause is a strained muscle or tendon or a sprained ligament, the pain will usually be accompanied by swelling and tenderness at the joint and by difficulty using the shoulder for routine everyday functions. Other possible causes could be a shoulder dislocation or a bone fracture. Yet another common cause of such pain is shoulder arthritis, bursitis or tendonitis. A doctor will be able to diagnose the precise cause of the pain. A shoulder brace could be the perfect device to stabilize the injured bones, ligaments or other structures and allow them the chance to heal fully.
