Shoulder joints can have their fair share of problems. Learn about common problems and injuries, and tips on how to treat a painful shoulder.

Although the shoulder is the most movable joint in the body, it is also an unstable joint because of its range-of-motion. Because the ball of the upper arm is larger than the socket of the shoulder, it is susceptible to injury.
Shoulder pain can arise from conditions inside the joints, in muscles or tendons, or from problems unrelated to the shoulder such as spine problems or heart conditions. Shoulder pain that is related to structures outside the shoulder is called referred pain.
Your shoulder joint is composed of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone). Your shoulders are the most movable joints in your body.
Your shoulder joint (glenohumeral joint) forms where your clavicle, humerus and scapula meet. This structure is why you can move your arms.
The shoulder complex is the connection of the upper arm and the thorax. Comprising numerous ligamentous and muscular structures, composed of the clavicle, scapula, humerus and sternum, and an intricately designed combination of four joints, the Glenohumeral (GH) Joint, the Acromioclavicular (AC)...
