Buttock pain is literally a pain felt in the posterior. Since many of us have sedentary jobs and buttocks that may just be a few sizes too big, the soft tissue surrounding the ischial tuberosity bones is compressed. The ischial tuberosity is the swollen part or broadening of the bone in the frontal portion of the ischium, the lowest of the three major bones that make up each half of the pelvis. As the point of fusion of the ischium and the pubis, it is attached to various muscles and supports the weight of the body when one is sitting.
How does buttock pain develop?
When we sit down, our buttocks usually rest on the ischial tuberosity. The most common cause of pain at the cheek line in the buttock area is weakness in the structures that attack to the ischial tuberosity. Buttock pain and tenderness over the ischial tuberosity is known in traditional medical lingo as ischial bursitis. Bursitis is an inflammation of the bursa, the fluid-filled sacs that allow tendons and muscles to glide over the bones. True bursitis is not only extremely rare, but also so painful that any pressure on the involved bursa would have the affected individual literally “hit the ceiling.” In other words, most buttock pain is not true bursisits but, rather, is due to a ligament injury and/or weakness in the area.
Buttock pain is most commonly seen in athletes involved in kicking or sprinting sports. It can occur in isolation or it may be associated with low back or posterior thigh pain. Pain in this region may arise from a number of local structures or be referred from the lumbar spine or sacroiliac joint.
