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 Symptoms. A frozen shoulder may or may not be associated with pain in the shoulder. Initial pain and tenderness may resolve and leave the shoulder with painless but limited range of motion. The scarring of the shoulder joint capsule may limit the ability to move the shoulder fully in all directions.
