When that shoulder aches too much to move

When that shoulder aches too much to move: Adhesive capsulitis, sometimes described as "frozen shoulder," is a condition where the connective tissue around the shoulder joint becomes chronically inflamed, causing thickening and tightening in the affected joint. Diagnosing adhesive capsulitis can be difficult because its symptoms -- restricted movement and considerable pain -- are similar to a variety of shoulder-related musculoskeletal conditions, including arthritis. Proper diagnosis of adhesive capsulitis may require extensive investigation into the patient's medical history to eliminate other causes.
