Shoulder pain can originate from either the joint of the shoulder or one of the many muscles, ligaments, or tendons surrounding it. Usually, shoulder pain caused by a joint worsens with activities or movement of the arm or shoulder, which is why patients seek out services such as shoulder overuse treatment.
Not all shoulder pain comes from injury, however. The pain in your shoulder may also be caused by diseases and conditions of your chest or abdomen, such as heart disease and gallbladder disease. Such referred pain is often associated with other structures. Shoulder pain caused by referred pain usually doesn’t get worse when you move your shoulder, and shoulder or rotator cuff treatment won’t get to the root of the problem.
