Adhesive capsulitis, commonly known as frozen shoulder, is a very painful condition. Not only is it painful but it gets progressively more stiff. The shoulder or glenohumeral joint is a capsule of connective tissue and this capsule can become inflamed after an injury or consistent overuse. Inflammation occurs in the soft tissues of the joint capsule and its synovial fluid. This leads to fibrosis and adhesions of the joint capsule and its synovial lining. X-ray findings of the bony structures of the shoulder remain negative.
