Causes of frozen shoulder. Frozen shoulder occurs when the sleeve that surrounds the shoulder joint, known as the capsule, becomes swollen and thickened. It's unclear why this happens. The shoulder is a ball and socket joint. The end of your upper arm bone (humerus) sits in contact with the socket of your shoulder blade (scapula).
Frozen shoulder can usually be diagnosed through a physical exam, but your physician may also order X-rays or additional tests to rule out other causes of your shoulder pain or limited motion. Treatment for frozen shoulder usually includes physical therapy to increase motion and anti-inflammatory medications to reduce pain.
