The ischial bursa is a synovial bursa located between gluteus maximus muscle and ischial tuberosity. [4] When in a seated position, the ischial bursa is put under the highest amount of pressure, which is most significant against a hard surface. [3] Friction from exercise can lead to inflammation of the ischial bursa, known as bursitis. [1]
For example, sitting pain is associated with sciatic nerve entrapment under the piriformis, but pain lateral to the ischium when walking is associated with ischiofemoral impingement. [1] The core of the physical examination is palpation and stretch/activation tests of the external hip rotators.
The ischial tuberosity (or tuberosity of the ischium, tuber ischiadicum), also known colloquially as the sit bones or sitz bones, [1] or as a pair the sitting bones, [2] is a large posterior bony protuberance on the superior ramus of the ischium. It marks the lateral boundary of the pelvic outlet.

It arises by tendinous fibers from the inner and forepart of the ischial tuberosity and, running medially, is inserted into the central tendinous point of the perineum (perineal body), joining in this situation with the muscle of the opposite side, with the external anal sphincter muscle behind, and with the bulbospongiosus muscle in front.
There is a relationship between the common stalk of the inferior gluteal nerve and external anatomic landmarks. The targeted region should be aimed inferior to the most prominent aspect of the greater trochanter, and medial to the landmark of the ischial tuberosity, at the depth of the posterior border of the proximal femur. Triangulating using ...
Pain while sitting is a well known symptom when having ischial tuberosity [12] pain, myofascial pain syndrome, coccyx pain , failed back surgery, arachnoiditis, sciatica, piriformis syndrome, and back pain in general. An inability to sit is one of the signs of chronic low back pain. [13]
