Temporomandibular arthritis, commonly known as hook pain, is a syndrome of pain, impaired movement and other symptoms caused by dysfunction or structural damage to the temporomandibular joint. The symptoms are pain deep in front of the ear and can radiate from there and spread to the whole side of the face, with a dull pain of mild or moderate nature. If it occurs in young adults, the diagnosis is: temporomandibular joint disorder syndrome. The etiology and pathogenesis of this disease are not fully understood by modern medicine, and there is a lack of curative methods in the treatment. Chinese medical theory suggests that the onset of this disease is related to liver and kidney deficiency and wind and cold attack. Because the liver is the main tendon, the kidney is the main bone, liver and kidney deficiency, the tendons and bones are flaccid, and lose their restraining power, and wind and cold attack, stay in the meridians, blocking the qi and blood, resulting in the tendons and ligaments lose nourishment, constricted as pain, so the symptoms are born. However, clinical treatment observation shows that the efficacy of simple Chinese medicine treatment for this disease is still unsatisfactory. I found through years of acupuncture medical treatment: the occurrence of the disease is related to the paralysis and obstruction of the meridians of the Directing Vessel and the Sun meridian, as long as the relevant paralysis and obstruction of the meridians can be unblocked, that is, to achieve the ideal near and long-term results. Of course, in addition to the most common cervical spine misalignment, there are other causes, which need to be carefully identified and differentiated during treatment. So what is the basis for treating the disease? Or why does the blockage of the meridians of the Directing Vessel and the Hand-Sun meridian cause the disease? The Directing Vessel is distributed along the median line of the back, and the Hand-Sun meridian meets the Directing Vessel at the Dazhi point (the lower edge of the spinous process of the seventh cervical vertebra in the median line of the back). Then, from the lateral edge of the neck, it is distributed upward along the front and back of the auricle to the front of the ear in the lateral region including the temporomandibular joint. The Hand and Sun meet at the Directing Vessel, which is relied upon to regulate the distribution and circulation of its own Yang energy. The relationship between the Directing Vessel and the Hand and Foot Yang meridians is similar to the relationship between the Yangtze River and the Yellow River in our country and the tributaries along them. The Yangtze River and the Yellow River are rich in water, the tributaries have sufficient water; too much local rainfall, the tributary water overflow can flow back to the Yangtze River and the Yellow River and be regulated. The inability of the upper part of the Directing Vessel can affect the flow of qi and blood in the nearby Hand-Sun meridian, which in time can also lead to paralysis of the Hand-Sun meridian. This eventually leads to pain and dysfunction of the temporomandibular joint, which can also be accompanied by temporal pain, dizziness and tinnitus, all of which are related to the distribution and circulation of the hand-sun meridian. Therefore, as long as the paralysis and obstruction of the Directing Vessel and the Hand-Sun meridian are cleared in a timely manner, the pain and dysfunction of the temporomandibular joint, as well as the symptoms of temporal pain, dizziness and tinnitus, can disappear, which is not at all unusual in Chinese medicine.
