The pain may be caused by inflammation or inflammatory masses in the buttocks. Pay attention to whether there is a mass in the buttocks, whether there is a lump, a red surface or a surface with pus head or pus flowing. If the pain is caused by an inflammatory mass, oral antibiotic treatment is usually sufficient to stop the pain, and oral painkillers, such as Celecoxib, can also be taken when the pain is obvious. If there is an internal abscess formation, it is necessary to perform an abscess incision under local anesthesia to drain the pus completely, fill the wound with gauze, change the medication and other treatments. The pain may also be caused by the compression of the sciatic nerve, which is usually caused by lumbar disc herniation.
