Buttock pain may be caused by physiological reasons such as long-term pressure and strain, or it may be caused by pathological factors such as hip joint diseases and lumbar diseases. 1. Physiological reasons: the hip is covered with rich myofascial tissue, responsible for cushioning the body weight. People who stand for a long time and sit for a long time or carry out large amount of sports activities for a long time may cause tension, fatigue or long-term pressure on the soft tissues of the hip, resulting in slowing down of local blood circulation and accumulation of metabolites, which will lead to the symptoms of hip pain. 2. Pathological factors: there are hip joints on both sides of the buttocks, which are responsible for connecting the pelvis and the femur, and if there are lesions in the hip joints, the symptoms of buttock pain may also appear, such as necrosis of the head of the femur, dislocation of the hip joints, etc.; lumbar diseases may produce pressure on the nerves innervating the buttocks, and the above symptoms may also appear, such as lumbar disc herniation, spinal stenosis and so on. The symptoms of buttock pain alone sometimes can not accurately determine the cause, but also need to be combined with the characteristics of the medical history, other test results in order to make an accurate judgment, it is recommended to clarify the cause of the disease under the guidance of the doctor, and comply with the doctor’s instructions to standardize the treatment.
