Pain in the buttocks is often gradual onset and can include piriformis syndrome, myofascial pain or pain referred from the lower back or sacroiliac joint. Direct impact can cause a contusion or bruising.
Piriformis syndrome causes pain in the buttock which may radiate down the leg. It is due to the sciatic nerve being impinged by a tight piriformis muscle deep in the buttocks.
The Sacroiliac joint is located at the bottom and just to the side of the back. They can become inflamed and painful. We explain the condition including symptoms and treatment.
Ischiogluteal bursitis is inflammation of the bursa that lies between the Ischial tuberosity and the tendon of a hamstring muscle.
Myofascial pain or trigger points in the Gluteus medius and Piriformis muscles can cause pain in the buttock area. A trigger point is a tiny localized knot in the muscle.
Bruised buttocks or a contusion of the buttocks is bleeding in the muscles caused by a direct impact to the area. This can be from a fall or being hit in the area by a hard blunt object such as a hard ball.
A pelvis avulsion fracture is where the tendon comes away from the bone often taking a piece of bone with it. This most commonly occurs at the ischial tuberosity where the hamstrings attach or the AIIS at the front where the Rectus Femoris attaches.
