Acupuncture treatment for pyriformis syndrome is usually performed on the hip’s ring-jump point and on the popliteal fossa of the back of the knee, with additional points being used according to the symptoms. Piriformis syndrome is a group of syndromes in which the sciatic nerve is compressed or chronically injured when it passes through the outlet of the piriformis muscle. According to Chinese medicine, this disease is caused by injury to the tendons and veins, resulting in stagnation of qi and blood, which leads to the passage of qi and blood. In clinical practice, the Huanjiu acupoint located in the buttocks and the Huizhong acupoint located in the popliteal fossa of the back of the knee area are usually selected as the effective acupoints for treatment. Huanjiu is an acupoint of the foot Shaoyang bile meridian, located at the intersection of the outer one-third and inner two-thirds of the line connecting the sacral fissure and the most convex point of the greater trochanter of the femur, and its location is the projection point of the sciatic nerve on the surface of the body. Therefore, the selection of this point has an obvious local therapeutic effect, dredging qi and blood to relieve pain. As the bladder meridian passes through the distribution area of the sciatic nerve, according to the Four General Acupuncture Points Song, the point is also of great clinical efficacy. Generally speaking, the most effective acupuncture points for the treatment of pyriformis syndrome are the Huanjiu and Huizhong points. Acupuncture treatment requires a high level of skill, so if you need to carry out acupuncture operations, you must go to a regular hospital, and not blindly operate on your own.
