Frozen shoulder (adhesive capsulitis) is stiffness, pain, and limited range of movement in your shoulder. It may happen after an injury or overuse or from a disease such as diabetes or a stroke. The tissues around the joint stiffen, scar tissue forms, and shoulder movements become difficult and painful. The condition usually comes on slowly, then goes away slowly over the course of a year or more.
Treatment for frozen shoulder usually starts with nonsteroidal anti-inflammatory drugs (NSAIDs) and application of heat to the affected area, followed by gentle stretching. Ice and medicines (including corticosteroid injections) may also be used to reduce pain and swelling. And physical therapy can help increase your range of motion. A frozen shoulder can take a year or more to get better.
If treatment is not helping, surgery is sometimes done to loosen some of the tight tissues around the shoulder. Two surgeries are often done. In one surgery, called manipulation under anesthesia, you are put to sleep and then your arm is moved into positions that stretch the tight tissue. The other surgery uses an arthroscope to cut through tight tissues and scar tissue. These surgeries can both be done at the same time.
