The common causes of hard pressure pain in the buttocks are intramuscular tumors, intramuscular soft tissue infections as well as sciatic nodes and bursitis, etc. Patients can clarify whether there are infections or tumors in the buttocks through buttock ultrasound and magnetic resonance examination, and may need to carry out puncture biopsy of tumor tissues if necessary in order to make a clear diagnosis. In addition, the most common cause of hip pain is sciatic node bursitis, which is mainly caused by patients sitting on a hard bench for a long time, and chronic inflammation of sciatic node and bursa occurs due to long-term pressure, which leads to pain and swelling, and can be treated by patients through rest, physical therapy, massage, and taking non-steroidal anti-inflammatory drugs.
