A bursa is a closed, fluid-filled sac that functions as a cushion and gliding surface to reduce friction between tissues of the body. Ischiogluteal bursitis is a result of inflammation of the bursa located between the origin of the hamstring muscle and the ischial tuberosity. It is often a result of a traumatic injury or direct blow to the bursa such as falling on a hard surface. Sitting for a prolonged period on a hard surface can also cause increased wear and tear on the bursa which will develop into bursal thickening, inflammation and tight muscles around the bursa. Activities such as walking, running and stair climbing are all common aggravating factors for this injury.
Signs and Symptoms:
- Generally produces a dull ache in the buttock which may become sharp pain with movements of the hip.
- Pain may radiate to the outside of the thigh.
- Extreme difficulty in sitting when acute.
- Altered gait pattern due to tight muscles around inflamed bursa.
