腹痛和腹胀。病症归属于中焦脾胃（中宫）。脏腑之气相互冲击，邪气与正气交相攻伐。兼夹寒邪或热邪，症状表现各不相同。说是饮食停滞或是积滞，壅塞阻滞于胸膈。有虚证也有实证，其成因难以穷尽。
这两种病的病因，各自按照类别归纳。先详细论述腹痛，病势好像攻击中焦。脾虚导致气冷，胃虚导致呕吐。虚热证见面色发黄，实热证见面色发红。食积证见大便臭秽，蛊积（寄生虫积聚）证见口吐沫涎。肝木乘克脾土，两胁部疼痛不适。寒水反侮脾土，腹泻痢疾严重。脾气下陷，感觉沉重坠胀如钟。脾来克制肾，少腹部像捣米一样疼痛。盘肠内吊（肠痉挛），腰部弯曲如同弓形。啼哭无泪嘴唇发黑，是由于肝风所致。
也有锁肚（胎便不下），腹部硬如石头。撮口（口唇紧缩难张），面色青紫。初生婴儿患此症，这两类病症，患病确实凶险。以上种种情况，务必疏通其中焦气机。其次详细论述腹胀，痞气填塞心胸。胸闷烦乱气喘胀满。若误用泻法则导致虚弱癃闭。土虚及肺，肺气消损。眼睑腮帮肿胀，内部波及喉咙。或者因为病后，脉象细弱朦胧。或者因为痰食，膈部满闷肚子壅塞。或者因为热结，高热如火烘烤。或者因为寒积，四肢冰冷流涎。丁奚病、哺露病、无辜病丛生，头小肚子大，身体黄瘦。这是胀病的重症，病气日益充盈。审察其根源，不要让病情加重。该补还是该泻，应当使病情缓解。不要当作平常小事，要用这些方法拯救幼儿。
钱乙说：小儿的积痛、食痛、虚痛、虫痛，大同小异。只有虫痛表现为口淡且自动流出沫涎。治疗时根据症状用药。虫痛与痫证相似。小儿本性怯弱，所以胃虚冷时，虫动而心痛，与痫证略微相似。但眼睛不斜视，手脚不抽搐。适宜用安虫散。又有胃受到极寒或极热的影响，也会导致虫病。有时轻微疼痛，有时不痛，突然吐出虫子。治法应当以安虫为主。如果因为治疗虫痛反而损伤胃气，那是不可以的。因寒而动者，用理中汤加乌梅、川椒。因热而动者，用五苓散加乌梅。
曾氏说：虫痛，小儿多有发生。其症状是心腹疼痛，叫哭，倒身扑打双手，呕吐清水和沫涎，面色青黄，时作时止。口唇呈紫黑色的，是蛔厥证。适宜用安虫散、安虫丸。
谭殊圣说：小儿腹痛，多因邪正交攻，与脏腑之气相互冲击而发作。桔梗枳壳汤加青皮、陈皮、木香、当归为妙。挟热而痛的，必然面色红赤壮热，四肢烦躁，手足心热。用四顺清凉饮加青皮、枳壳。挟冷而痛的，必然面色或白或青，手脚冰冷。用七气汤加桂枝，调服苏合丸。冷甚变症，则面色黯黑，嘴唇口角都发黑，指甲皆青。若是内吊痛，则用钩藤散。其余情况则用芍药甘草汤，都是重要药物。
Abdominal pain and abdominal distension. The disease belongs to the Middle Jiao (Central Palace, referring to the Spleen and Stomach). Visceral Qi strikes each other; pathogenic factors and healthy Qi attack mutually. Accompanied by cold or heat, symptoms present differently. It is said to be food stagnation or accumulation, obstructing in the chest. There are deficiency and excess patterns, their causes are difficult to exhaust.
The causes of these two diseases follow their respective categories. First, detail abdominal pain: the momentum seems to attack the center. Spleen deficiency leads to Qi cold; Stomach deficiency leads to vomiting. Deficiency-heat presents with a yellow complexion; Excess-heat presents with a red complexion. Food stagnation presents with foul-smelling stool; Gu accumulation (parasitic accumulation) presents with foaming from the mouth. Liver Wood overacting on Spleen Earth causes dull pain in both hypochondria. Cold Water insulting Spleen Earth causes severe diarrhea and dysentery. Spleen Qi sinking causes a heavy, dragging sensation like a bell. Spley attacking Kidney causes the lower abdomen to feel as if being pounded. Intestinal colic (internal hanging intestines) with the waist curved like a bow. Crying without tears and black lips are due to Liver Wind.
There is also "Lock Belly" (failure to pass meconium), where the abdomen is hard as stone. "Mouth pinching" (tightening of the lips/mouth) with a cyan complexion. In newborns, these two conditions are truly ominous. For all the above situations, it is essential to unblock the middle Jiao. Next, detail abdominal distension: Pi Qi (stagnant Qi) fills the chest and heart. Chest oppression, confusion, wheezing, and fullness. If purged incorrectly, it leads to weakness and urinary retention. Earth deficiency affecting Lung Metal causes Metal Qi to melt. Eyelids and cheeks swell, internally involving the throat. Or due to post-illness, the pulse is fine and hazy. Or due to phlegm and food, the diaphragm is full and the belly is obstructed. Or due to heat binding, high fever like roasting. Or due to cold accumulation, cold limbs and salivation. Ding Xi, Bu Lu, and Wu Gu diseases cluster together; small head, large belly, yellow and emaciated body. This is a severe stage of distension, with pathogenic Qi filling daily. Examine the root cause, do not allow the disease to flourish. Whether tonifying or purging, the disease should relax. Do not treat it lightly; use this to save the child.
Qian Yi said: Children's Ji pain (accumulation pain), Shi pain (food pain), Xu pain (deficiency pain), and Chong pain (worm pain) are largely similar with minor differences. Only worm pain presents with a bland taste and spontaneous foaming. Treatment depends on the symptoms. Worm pain resembles epilepsy. Children are naturally timid; thus, when the Stomach is deficient and cold, worms move causing heart pain, slightly resembling epilepsy. However, the eyes do not deviate, and hands/feet do not convulse. An Chong San (Worm-Calming Powder) is suitable. Also, extreme cold or heat affecting the Stomach can cause worm disease. Sometimes mild pain, sometimes no pain, suddenly vomiting worms. The method should focus on calming worms. If treating worms damages Stomach Qi, it is inadvisable. For movement due to cold, Li Zhong Tang (Regulate the Middle Decoction) plus Wumei (Mume Fruit) and Chuanjiao (Sichuan Pepper). For movement due to heat, Wu Ling San (Five-Ingredient Powder with Poria) plus Wumei.
Zeng said: Worm pain is common in children. Symptoms include heart and abdominal pain, crying, throwing the body and hitting hands, vomiting clear water and foam, greenish-yellow complexion, intermittent onset and cessation. Those with purple-black lips have Hui Jue (Roundworm Jue). An Chong San (Worm-Calming Powder) and An Chong Wan (Worm-Calming Pill) are suitable.
Tan Shusheng said: Children's abdominal pain is often caused by the mutual attack of pathogenic and healthy Qi, striking visceral Qi. Jiegeng Zhike Tang (Platycodon and Bitter Orange Decoction) added with Qingpi (Green Tangerine Peel), Chenpi (Aged Tangerine Peel), Muxiang (Costus Root), and Danggui (Angelica Sinensis) is excellent. Pain with heat binding必然 (necessarily) presents with red face, high fever, restless limbs, and hot palms/soles. Sishun Qingliang Yin (Four-Smooth Cooling Decoction) added with Qingpi and Zhike (Bitter Orange). Pain with cold binding necessarily presents with white or cyan face and cold extremities. Qi Qi Tang (Seven-Qi Decoction) added with Guizhi (Cinnamon Twig), mixed with Suhe Wan (Styrax Pill). If cold becomes severe and changes symptoms, the face darkens, lips and mouth turn black, and nails become cyan. For internal hanging pain, Gouteng San (Uncaria Powder) is used. For others, Shaoyao Gancao Tang (Peony and Licorice Decoction) is used; these are all important formulas.
