Frozen shoulder, or adhesive capsulitis, is a condition that creates pain and stiffness in the shoulder joint, severely limiting your ability to move your shoulder normally. When this happens, your shoulder feels like it is "frozen" in place. You probably will have difficulty raising your arm in front of you or putting your hand behind your head or back.

Frozen shoulder occurs when there is a problem with the capsule that surrounds your shoulder joint. Sometimes the capsule thickens or decreases in size, restricting the joint.

The result is a lack of mobility and severe pain.
