Hip bursitis is a painful condition caused by inflammation of a bursa in the hip. Bursae are fluid filled sacs present in joints between bone and soft tissue to reduce friction and provide cushioning during movement. Trochanteric bursitis is often seen in people involved in sports such as football and soccer which involve a lot of running. This can lead to overuse and irritation of the bursa causing inflammation. Bursitis may sometimes result from an injury or fall to the hip or after a surgical procedure of the hip.
