What is Shoulder Pain?
Shoulder pain occurs when the muscles, tendons or ligaments in your shoulder become overused and irritated. You may experience shoulder pain as a result of injury—such as by overstretching your arm—or from repetitive use, from activities like painting, throwing a ball, or even brushing your teeth. The most common cause of shoulder pain happens when the rotator cuff tendons are trapped under the bony part of the shoulder. When this occurs the tendons experience inflammation or damage. You also may experience shoulder pain as a result of a chronic disease or age-related condition.
