Half of the buttock pain is commonly associated with gluteus medius syndrome, which is located on the lateral aspect of the iliac wing, with the first 2/3 of it being triangular in shape and the last 1/3 being feather-shaped. This muscle can stabilize the pelvis when the body is standing, thus stabilizing the entire trunk, and plays a very important role especially in the process of daily walking, when landing on one foot. In daily life, the gluteus medius plays a very important role in bending, standing upright, walking, squatting, and all these actions. If the gluteus medius muscle is injured, it is easy to have hip pain, especially late at night and in the morning, and the pain is obvious after exertion or cold, and sometimes it spreads to the outer thighs. There are obvious signs of pressure on the nerve roots. If the lumbar spine MRI does not show this, and there is no other symptom in the lumbar area, the gluteus medius syndrome is generally considered. The main treatment method is to take sufficient rest, which can be done through physiotherapy, massage and massage, and then assisted by anti-inflammatory and analgesic drugs, most of which can achieve good treatment effect. For the more serious cases of gluteus medius syndrome, closed or small needle knife can be used, and if necessary, surgery can be performed to remove the painful fascia or to release the gluteal membrane.
