Bursitis of the Hip

Bursitis of the hip is inflammation of one or both of the bursae (plural of bursa) found between the hip bone and the muscles on the outside of the hip.

A bursa is a fluid-filled sac that cushions and lubricates areas of the body where friction is likely to occur. Examples of such areas include between two bones, between a tendon or ligament and a bone, and between bone and skin.
