Bursitis

Definition of Bursitis

Bursitis is inflammation of the fluid-filled sac (bursa) that lies between a tendon and skin, or between a tendon and bone. The condition may be acute or chronic.

Causes, incidence, and risk factors

Bursae are fluid-filled cavities near joints where tendons or muscles pass over bony projections. They assist movement and reduce friction between moving parts.

Treatment

Your health care provider may recommend temporary rest or immobilization of the affected joint.

Expectations (prognosis)

The condition may respond well to treatment, or it may develop into a chronic condition if the underlying cause cannot be corrected.
