What Causes Frozen Shoulder?

by Shearly (SU)
Adhesive capsulitis is the scientific name for frozen shoulder, which is a painful condition affecting the shoulder joint. The shoulder is a joint that is made up of three bones: the humerus, scapula, and clavicle (upper arm, shoulder blade, and collarbone). Holding this ball and socket joint together is tissue that is referred to as the shoulder capsule. Frozen shoulder affects this area. The stiffness and pain associated with frozen shoulder will often come on gradually, making it difficult to diagnose or predict. The condition can sometimes get worse before it gets better, lasting up to three years.
