What is a Frozen Shoulder?

Have you felt nagging pain and stiffness in your shoulder? If so, you may have frozen shoulder. This problem is sometimes called adhesive capsulitis. It is not well understood. But it often improves over time with treatment.
Your shoulder is a joint that is made up of many parts. They help you raise, rotate, and swing your arm. But is you have frozen shoulder, certain parts of the shoulder joint contract (shrink and pull in). This often causes pain and stiffness when you try to move your arm.
