Frozen shoulder (adhesive capsulitis) is stiffness, pain and limited range of movement in your shoulder that may follow an injury.  The joint capsule and tissues around the joint stiffen, scar tissue forms, and shoulder movements become difficult and painful. Frozen shoulder can develop when you stop using the joint normally because of pain, injury, or a chronic health condition, such as diabetes or arthritis.  Any shoulder problem can lead to frozen shoulder if you do not work to maintain full range of motion.

Frozen shoulder occurs:

• After surgery or injury.
• Most often in people 40 to 70 years old.
• More often in women (especially in postmenopausal women) than men.
• Most often in people with chronic diseases.
