【歌】寒痛绵绵无减增,时疼时止热为根。血瘀痛处无移动,食积便通便见轻。实者不能将手近,痛时
能按作虚论。湿痰痛者溲便秘,体认其形见病情。
【论】夫寒痛者,常痛而无增减也,成无己云∶阴寒为邪,则腹痛而吐利。热痛者,时作时止,《原病》
式云∶热郁于内,而腹满坚结痛,勿以为寒。死血痛者,每痛不移其处,成无己云∶邪气聚于下焦,津液不得
通,气血不得行,或溺或血,留滞于下,是生胀硬,小便不利也。食积痛者,利后即痛减。湿痰痛者,凡痛,
大、小便俱不利,丹溪云∶清痰多作腹痛,脉滑,痰因气滞而聚凝,其道路不得通故也。肠痈痛者,身甲错,
小便如淋,腹皮急,按之濡,如肿状,脉芤数也。积聚腹痛者,腹中原有积,左、右、上、下当积而痛也。寒
疝入腹痛者,少腹痛引睾丸。阴毒痛者,四肢厥逆,痛甚,咽喉不利,或心下胀满结燥,虚汗狂言,面色俱青,
阴积于下,阳消于上。实痛者,腹坚不可按。虚痛者,虽痛不胀满,手可按。若此霄壤不侔,可一药而尽之乎?
谨按∶腹痛,为脾家受病,盖脾或受有形而痛者,或受无形而痛者。若暴伤饮食,则胃脘先痛而后入腹。暴触怒
气,则两胁先痛而后入腹。血积上焦,脾火熏蒸,则痛从腹而上于胸臆。血积下部,胃气下行,则痛从腹而入
于少腹。伤于寒者,寒于痛,得热则缓。伤于饥者,饥即痛,得食即止。吞酸腹痛,为痰郁中焦,复伤饮食。
面黄腹痛,为宿食不消,蛔虫攻咬。气虚腹痛,腹必虚豁,呼吸短浅。血虚腹痛者,痛如芒刺,牵引不宁。医
者当审其因以处治,大要以甘温为上,惟伤酒作痛者,方可凉剂,而必佐之以甘温也。

[Verse] Cold-type abdominal pain presents as a continuous, lingering ache without significant fluctuation in intensity. Abdominal pain that comes and goes is often rooted in heat. Pain caused by blood stasis remains fixed in one location. Pain due to food stagnation alleviates after defecation. In excess-type abdominal pain, the abdomen is hard and patients refuse pressure; if pressing relieves the pain, it should be diagnosed as deficiency. Pain from damp-phlegm is accompanied by constipation of both urine and stool, and can be identified by observing the patient's physique.
[Dissertation] Cold-type abdominal pain is typically persistent without severe fluctuations. Cheng Wuji stated: "When Yin-cold pathogenic factors invade, abdominal pain occurs accompanied by vomiting and diarrhea." Heat-type abdominal pain manifests intermittently. The *Yuan Bing Shi* states: "Heat constrained internally causes abdominal fullness, hardness, and pain; do not mistake this for cold." Pain from stagnant blood (blood stasis) does not shift location. Cheng Wuji said: "Pathogenic factors gather in the Lower Jiao, preventing the free flow of body fluids and Qi-blood. This may lead to urinary or fecal abnormalities, stagnation in the lower region, resulting in distension and hardness, and difficult urination." Pain from food stagnation alleviates after purging. Pain from damp-phlegm involves obstruction of both urination and defecation. Danxi stated: "Clear phlegm often causes abdominal pain with a slippery pulse; this is because phlegm condenses due to Qi stagnation, blocking the pathways." Intestinal abscess pain presents with rough, scaly skin (like fish scales), frequent urgent urination resembling strangury, tense abdominal wall that feels soft upon palpation (suggesting swelling), and a cun-kou pulse that is hollow and rapid. Accumulation-induced abdominal pain arises from pre-existing masses within the abdomen, with pain occurring at the site of the mass (left, right, upper, or lower). Cold hernia entering the abdomen causes pain in the Shaoyang region radiating to the testicles. Yin-toxin pain presents with cold extremities, severe pain, throat discomfort, epigastric fullness and dryness, spontaneous sweating, delirium, and a bluish complexion. This indicates Yin-cold accumulating below and Yang Qi declining above. Excess-type abdominal pain features a hard abdomen that cannot be pressed. Deficiency-type abdominal pain involves pain without fullness, allowing for gentle pressure. Given the vast difference between these two conditions, how can a single formula treat all cases?
Note: Abdominal pain is primarily a disorder of the Spleen. The Spleen may be affected by tangible pathogens or intangible pathogens. If injured suddenly by diet, pain starts in the Stomach region before spreading to the abdomen. If provoked suddenly by anger, pain starts in the hypochondrium before spreading to the abdomen. Blood accumulation in the Upper Jiao, steamed by Spleen fire, causes pain to radiate from the abdomen upward to the chest. Blood accumulation in the lower part, combined with descending Stomach Qi, causes pain to move from the abdomen into the lower abdomen. Cold injury causes pain that worsens with cold and alleviates with warmth. Hunger causes pain that stops upon eating. Acid regurgitation with abdominal pain results from phlegm-dampness constrained in the Middle Jiao compounded by dietary injury. Yellowish complexion with abdominal pain indicates undigested food and roundworm attack. Qi-deficiency abdominal pain presents with a feeling of emptiness in the abdomen and shortness of breath. Blood-deficiency abdominal pain feels like needle pricks with restless pulling sensations. Physicians must examine the cause for treatment. Generally, sweet-warm herbs are preferred. Only in cases of alcohol-induced pain are cooling formulas used, but they must still be supplemented with sweet-warm herbs.
[Pulse Diagnosis] Deep, wiry, fine, and moving pulses are all indicative of pain syndromes. Heart pain is reflected in the Cun position, abdominal pain in the Guan position, and lower body pain in the Chi position; the pulse signs are clear.
Heat-Type Abdominal Pain
Heat in the chest and pathogenic factors in the stomach, causing abdominal pain and nausea, are treated with Huanglian Tang (Coptis Decoction). Abdominal pain with a surging pulse indicates heat, treated with Huangqin Shaoyao Tang (Scutellaria and Peony Decoction).

Abdominal fullness with intermittent pain is treated with Guizhi Jiadahuang Tang (Cinnamon Twig Decoction plus Rhubarb). Abdominal pain with constipation and a large, excess pulse is treated with Dachengqi Tang (Major Order the Qi Decoction). (See Food Stagnation section for formulas.)
