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).
The shoulder capsule is fully stretched when you raise your arm above your head, and hangs down as a small pouch when your arm is lowered.
In frozen shoulder, bands of scar tissue form inside the shoulder capsule, causing it to thicken, swell and tighten. This means there's less space for your upper arm bone in the joint, which limits movements.
It'snot fully understood why frozen shoulder occurs, and it'snotalways possible to identify a cause. However,a number offactors canincrease your risk of developing it. These are outlined below.
