The *Suwen·Zangqi Fashi Lun* (Plain Questions · Treatise on the Correspondence of Visceral Qi with the Four Seasons) states: "Liver disease manifests with pain in both flanks (xie), which radiates to the lower abdomen, and a tendency to anger. Why is this?" This is because the Liver Jueyin channel runs upward from the foot, encircles the external genitalia and reaches the lower abdomen, then ascends further to penetrate the liver and diaphragm, and distributes to the costal and hypochondriac regions. Therefore, pain below both flanks radiates to the lower abdomen. The *Cire Pian* (Chapter on Needling Heat Diseases) says: "Liver heat can also cause hypochondriac pain (xietong), with restlessness of the hands and feet, and inability to sleep peacefully." The *Ke Lun* (Treatise on Cough) states: "The manifestation of liver cough is that coughing causes pain below both flanks, and in severe cases, the body cannot turn; turning causes fullness below both flanks. Spleen cough can also cause pain below the right flank, with a dull ache radiating to the shoulder and back; 'xie' also refers to the costal region." The *Ju Tong Lun* (Treatise on Various Pains) says: "When cold qi lodges in the Jueyin channel, it causes hypochondriac pain radiating to the lower abdomen." Discussing from the perspective of annual qi (suiyun): "In a year of excessive wood (mu), if metal (jin) counteracts it, hypochondriac pain occurs. In a year of excessive fire (huo), if water (shui) counteracts it, there is chest pain and distending fullness and pain in the hypochondrium. In a year of excessive metal (jin), disease manifests with pain in both hypochondria and the lower abdomen. When wood overcomes metal and metal retaliates, there is sudden severe pain in the chest and hypochondrium, radiating downward to the lower abdomen." The *Liu Yuan Zheng Ji* (On the Regular Order of the Six Epochs and the Primary Qi) states: "When wood (mu) is depressed, disease arises in the stomach duct (weiwan), with pain at the heart region, supporting the two flanks upward, obstruction of the diaphragm and throat, and inability to ingest food and drink." The *Zhi Zhen Da Yao* (Great Treatise on the Ultimate Truth and Essential Principles) says: "When Yangming is in the earth (spring), there is heart and hypochondriac pain preventing turning over." The *Miu Ci Pian* (Chapter on Contralateral Needling) states: "When pathogenic factors invade the collaterals of the foot Shaoyang channel, it causes hypochondriac pain with inability to breathe freely, and cough with sweating. When pathogenic factors invade the collaterals of the foot Taiyang channel, it causes spasm and tension of the back, radiating to the hypochondrium and causing pain." The *Biao Ben Lun* (Treatise on the Root and Branch) says: "Heart disease first manifests as heart pain. After one day, it transmits to the lung via cough. After three days, the lung transmits to the liver, causing distending pain and fullness in the hypochondrium. Liver disease manifests as dizziness of the head and eyes, and distending fullness and pain in the hypochondrium." Moreover, the left and right flanks are the pathways of yin and yang. Therefore, the liver generates on the left, and the lung stores on the right. The left belongs to the liver, which stores blood. The liver is yang, blood is yin, thus it is externally yang and internally yin. The right belongs to the lung, which governs qi. The lung is yin, qi is yang, thus it is externally yin and internally yang. Some say that when liver blood accumulates on the left, forming a lump with pain in the flank, it is liver accumulation (ganji), named Feiqi Wan. When lung qi stagnates on the right, with stuffiness, hardness, and pain in the flank, and cough and panting, it is lung accumulation (feiji), named Xiben. The spleen is connected to the right, and its channel is prone to dampness excess, hence phlegm-rheum (tanyin). Dampness can transform into phlegm, which flows along the channel to the right. Pain in the left flank is mostly caused by retained blood. Pain in the right flank is entirely due to phlegm-qi. Can pain in both flanks be discussed in a generalized manner? When discussing the causes of disease, one should differentiate the external six excesses (liuyin) and the internal five pathogens (wuxie). For instance, sudden anger causing injury and disturbance, sorrow leading to qi binding, excessive eating and drinking, imbalance of cold and heat, falling and injuring the body, or phlegm accumulation flowing to the right and contending with blood, all can cause pain. Zhang Zhongjing discussed Cold Damage (Shanghan) Shaoyang disease, where severe deafness and hypochondriac pain occur; this is due to stagnation of liver-gallbladder qi causing pain. Moreover, the disease of hypochondriac pain has been discussed in detail in various classics. Regarding the pulse, wiry (xian) and choppy (se) are favorable, while flooding (hong) and large (da) are unfavorable.
The treatment method should consider the annual qi, differentiate left and right, distinguish between qi, blood, phlegm, and accumulation, assess the deficiency or excess of the bodily form and symptoms, and administer medicine accordingly. There is no case where efficacy is not achieved and a perfect result is obtained.
