The feeling of pain is innate, and anyone who feels pain is afraid of it. In Chinese, the word “pain” refers to residual pain, and “ache” refers to the injurious sensation inside the patient’s body. Since ancient times, pain has plagued mankind, therefore, a history of the development of Chinese medicine is also a history of the Chinese people’s struggle with pain. It can be said that, in the face of chronic pain, especially difficult pain, if you can apply the overall dialectical thinking of the motherland medicine to diagnosis and treatment, often can play a better effect than the simple application of modern medicine diagnosis and treatment. The motherland medicine thinks that the pain is due to the deficiency of the guards outside not solid, the evil gas takes advantage of the deficiency to enter, so that the blood stagnation, paralysis and blockage of the meridians and become. Su Wen: The Treatise on Paralysis” says: “Wind, cold and dampness are mixed together and become paralysis.” The Essay on Pain Lifting (Su Wen, The Essay on Pain Lifting) also says: “Cold enters the meridians and is delayed, weeping and not working; when it is outside the veins, there is less blood, and when it is in the veins, there is no access to the qi, so it is painful in a sudden manner.” The Spiritual Pivot: The Five Retained Liquids and Fluids” also says: “The fluids of the five grains, and together they make a paste, which penetrates into the bone and tonifies the brain and marrow, and flows down into the yin and femur. If the yin and yang are not in harmony, the fluid overflows and flows down to the yin, and the medulla is all reduced and goes down, and when it goes down excessively, it is deficient, and deficiencies cause pain in the lumbar and back and soreness in the shins.” This explains that the cause of pain is not limited to the two ends of the spectrum, the real being “pain if there is no circulation” and the virtual being “pain if there is no honor”. “Not through the pain” for the real pain key “not through the pain” is that the occurrence of pain regardless of the cause, are due to the evil blockage of the meridians, qi and blood is not smooth. Chinese medicine believes that the human body’s meridians and blood should be “more than popular, around and around”, if you suffer from external attack, it will cause blood stasis and blockage, so that the internal organs and meridians are out of order, the blood does not run smoothly, “not through the pain”. Its pathogenesis changes mainly in the following aspects. 1, gas blockage: gas for blood handsome, gas line is blood line. If emotional discomfort, indignation and depression, not stretching, desire, then the liver and qi stagnation, stagnation of qi and blood stasis. Qi stagnation in the chest can lead to distension and pain in the chest and hypochondrium; Qi stagnation in the upper jiao can lead to chest pain; Qi stagnation in the middle states can lead to stomach pain. Stagnant Qi in the lower abdomen causes abdominal pain; stagnant Qi in the uterus causes dysmenorrhea; stagnant Qi in the meridians causes pain in the limbs. The gas elevation rule section in the lungs, rise and drain in the liver, spleen and stomach for its hub, so the gas stagnation pain and the lungs, liver, spleen and the three organs have the closest relationship. 2, cold stagnation: cold collects and leads, stagnation, easy to cause the meridians to occur curled up, shortness of contracture, so that the qi and blood do not run smoothly and pain, especially the Yang qi is weak for the occurrence. Cold guest sun and hair headache, body bone pain; cold in the Taiyin and abdominal pain; cold attack Shaoyin and hair chest pain; cold in the syncopated yin and top pain; cold condensation meridian is limb muscle pain. 3, heat and evil congestion: “Jing” cloud “all diseases hock swelling, pain and acid shock, all belong to the fire.” It means that heat and evil congestion, positive and evil fight, it affects the operation of qi and blood, coupled with the blood burnt by heat and evil, blood heat and yin injury, so that the qi and blood do not run smoothly and congestion, can be issued as pain. Such as heat knot lung, lung injury is hair chest pain; heat depletion of liver and gallbladder, liver and gallbladder veins are burned coercive pain; liver fire through the channels on the disturbance of the clear orifices, can be seen in the head distension and pain, eye red pain; heat knot yangmings, viscera gas is not through the abdominal pain; hot offenders cardiac meridian, heat and stasis of mutual knotting of the pain of the heart; the heart of the fire down to move the small intestine, then the urine is red, burning pain; heat in the surface of the muscle, blocking the skin veins and blood skin burning pain; heat into the meridians and joints, and the qi and blood, resulting in the meridian Stagnant blockage of joints and limbs pain; heat evil congestion, heat and muscle, burnt blood, and then send sores, boils, swelling and pain, burning, such as carbuncle, skin boils and so on. 4, dampness obstruction: wet for Yin evil, heavy turbid viscous, most likely to block the qi, blocking qi and blood and hair pain. Dampness clear orifices, Qing Yang does not show, the blood does not run smoothly, the veins are blocked headache such as wrapping; dampness trapped spleen, so that the gas elevation is not normal, then the epigastric pain, diarrhea; dampness stagnation of the veins and not to go, so that the gas and blood blocked, and become paralyzed by the heavy pain. 5, dampness and heat vaporization: dampness and heat together, such as oil on the surface, wet and hot and deep, hot and wet and more blazing. Dampness and heat for the patient, the most likely to block the qi, up to disturb the injection, flowing meridians and channels, blocking the blood, so that the blood run poorly for a variety of pain. Dampness and heat vaporization in the upper, upward and into the meridians, so that the congestion of blood and clear and not work, so the hair head, ears, tongue, mouth, throat pain; Dampness and heat committed to the supra-jiao, paralysis of thoracic Yang, blocking the heart veins, thoracic Yang does not show the heart of the paralysis of the heart and blood blockage, the hair of the chest pain pain heartache; Dampness and heat is embedded in the middle of the jiao, or depressing in the liver and gallbladder, then the loss of the liver and gallbladder to its excretion of the jaundice, resulting in duress, jaundice, etc.; or trapping the spleen and stomach, the qi stagnant, the viscera Qi can not be, then the hypochondrium Pain; dampness and heat of the evil in the intestines, the qi is not smooth, conductive disorder, abdominal pain and dysentery; dampness and heat flow in the lower Jiao, or injection into the bladder, bladder qi is unfavorable, the urethra is not smooth, and for urinary pain and urgency; or injection into the Chong Ren, Chong Ren qi is unfavorable, and for the abdominal pain and bring down; or injected into the large intestine, then the piles, anal fissure, etc.. 6, phlegm obstruction of the veins: phlegm disease involves a variety of clinical disciplines, so China’s ancient medical doctors put forward “more than a hundred diseases by phlegm”, “all diseases and phlegm” and “phlegm for the disease, the illusion of a hundred ends,” and other academic insights. Academic insights. And because of the phlegm disease, phlegm evidence of the clinical manifestations of strange and bizarre, so there is “phlegm more strange disease” said. China’s ancient medical doctor Li Shizhen pointed out in the “Lake Pulse”: “phlegm born of a hundred diseases, food born of disaster”, which can be described as a phrase, the phlegm disease of the wide range of a high degree of generalization. When phlegm is injected into the brain and obstructs the normal operation of the head, it causes headache, heavy headache, dizziness and discomfort, which is more serious when it is cold and cloudy, with white and greasy tongue, anorexia of oily food and drinking a lot of water, which is known as “phlegm-convulsive headache” or “phlegm-dampness headache”. If phlegm is blocked in the heart and lungs, it can be seen as coughing and chest pain, chest tightness, and if phlegm flows in the chest and diaphragm, it can be seen as dystocia. Internal phlegm can block the flow of qi and blood, making the meridians and collaterals impassable, and the disease can be seen as heat in a certain part of the body, and coldness in some parts of the body, or numbness and numbness in some parts of the limbs. These pains can be treated by resolving phlegm. 7, blood stasis and blockage: Where the blood from the meridian can not be discharged and dissipated in a timely manner, stay in the body, or the line of blood is not smooth, congestion in the meridian, stasis in the internal organs and tissues, loss of its physiological function are called blood stasis. The modern view of blood stasis should include blood stagnation, blood flow, blood circulation disorders, the occurrence of all pathological changes in the development and secondary changes in the process of one of the body is inseparable from the gas and blood, the gas for the blood of the marshal, the blood for the mother of the gas. Where the disease pain after many days of treatment does not heal, must be when the blood for the regulation. Ye Tianshi that the first disease in the meridian, long-term disease into the complex, the main gas, the main blood. “Where the main gas meridian, the main blood, the blood of long illness,” put forward “long illness into the theory of”, advocating “through the” said. Some chronic diseases, chronic illnesses, intractable diseases, difficult pain such as (headache, lumbar and leg pain, rheumatism and rheumatoid disease), etc. often have a direct relationship with blood stasis, stasis of blood blockage of the meridians, so that qi and blood can not be fluent, so the back, waist, leg pain; tongue purple or dark or petechiae, pulse is thin and astringent, light day and night are all the stasis of blood within the stopping signs. Practice has also proved that by activating blood and removing stasis method of treatment can obtain good clinical efficacy. In addition, others, such as food accumulation, worms, stones stagnation in the body, can also affect the operation of qi and blood, not through the pain, and the formation of a variety of pain. “Does not honor the pain” for the key to the mechanism of deficiency pain “does not honor the pain” refers to the evil attack, or low visceral function, resulting in yin and yang, qi and blood loss, the human body viscera and veins lost in the warmth, moistening, and caused by the symptoms of pain. 1, weak yang qi, pulse loss warm: yang qi deficiency, qi and blood running powerless, or veins, blood stasis can not be issued as pain; or can not warm the internal organs and meridians, meridians and contractures and pain. 2, Yin and blood deficiency, loss of moistening of the veins: “blood main moistening”, blood deficiency can not be nutritious and moisturizing organs, body, nine orifices and other tissues and organs, tendons and veins are not nourished, the veins are constricted and the pain occurs. For the above pain mechanism, Chinese medicine can use different methods of diagnosis and treatment, can be taken internally and externally with traditional Chinese medicine. The external treatment of Chinese medicine is the characteristic therapy of Chinese medicine in treating pain, which includes acupuncture, massage, moxibustion, gua sha, acupoints, small needle knife, etc. In short, chronic pain, especially difficult pain, can be treated by the Chinese medicine practitioners. In conclusion, the etiology of chronic pain and especially difficult pain is very complex. We should not lose confidence and suffer in silence because we have simply seen a Chinese medicine practitioner or simply seen a Western medicine practitioner who has not solved the pain! We should tell our family, friends, and medical professionals around us in time to get everyone’s support and help!
