The meridian on the lateral thigh is mainly the foot Shaoyang bile meridian, one of the twelve meridians of the human body. At present, only TCM doctors use meridians to treat patients in clinical practice, but the use of meridians in clinical practice is relatively narrow at present, because most patients with neck, shoulder and back pain now use anatomical acupuncture, that is, acupuncture in TCM, and doctors also choose to learn the anatomy of Western medicine when treating patients with neck, shoulder and back pain, and then use acupuncture for patients through anatomical parts, and only when internal diseases are used Meridian acupuncture is only used for internal diseases. It is an independent system and only acupuncturists need to master meridians systematically.
