The reasons for the pain in the right buttock bone are as follows: 1. It may be due to lumbar disc herniation, so that the nerve roots are stimulated and compressed, and the pain in the nerve roots is radioactive, and the buttock is the part that is often involved, causing the pain in the buttock bone. 2. The pain will be more obvious if you sit on a hard bench or stay in an air-conditioned room. 4. If the injury is caused by trauma, the right femoral neck fracture or pelvic fracture may occur. If there are indications for surgery, active surgical treatment may be required to relieve the symptoms of bone pain inside the right buttock.
