Pain on both sides of the buttocks should be considered in the following cases: first, gluteal fasciitis: the main reason is prolonged sedentary, or frequent bending and working, which can cause strain on the gluteal fascia. The gluteal fascia is in a high tension state for a long time, which can easily cause the dermal nerve in and out of the gluteal fascia to be stuck, so it can manifest as pain in the buttocks, which is mostly distributed in pieces and symmetrical bilaterally, and can be more obvious after exertion and can be relieved after rest. Second, bilateral sciatic tubercle bursitis: it is mainly due to the pressure of the sciatic tubercle bone on the bursa below it when sitting for a long time. As the compression time is longer, it will cause inflammation of the bursa, manifesting as pain in the bilateral sciatic tuberosity area.
