: inflammation of a bursa (as of the shoulder or elbow)
Inflammation of the lubricating sac (bursa) over a joint or extension of a joint, or between tendons and muscles or bones, caused by infection, injury, arthritis or gout, calcium deposits along a tendon or joint, or repetitive minor irritation. Common types are housemaid's knee, soldier's heel, tennis elbow, and weaver's bottom. Bursitis in the shoulder is the most common form. Usually occurring in people unaccustomed to physical labour, it may be so painful that the affected part cannot be used. Treatment includes rest, heat, mild exercise, and medication to relieve inflammation and remove calcium deposits.
