〔曾〕 瘕痛，乃积久所致，由荣卫俱虚，外则感受风寒，内则过伤乳食，停滞既久，不能克化，故
邪并于阴为 ，阴则专静，凝而不移，邪并于阳为瘕，假物象
形，动而不息。若久而不治，亦成脾疳积，或两胁间有块如石，按之则痛，不按则轻。或面黄肌瘦，肚硬
而胀及有青筋，昼凉夜热，蒸潮无时，乳食减少，爱吃泥土。或大便酿泻，痛则身冷如冰。法当调脾养胃，用醒
脾散（慢惊）参苓白术散（不乳食）。磨积理疳，用化癖丸（癖）三棱散（宿食）木香莪术丸（宿食）。治酿泻，
没石子丸（泻）、沉香槟榔丸（癖积）。然此积滞之疾，非七剂可疗，必须次第调理，则日久自然平复。
〔曾〕始则腹内一小长块，其硬如臂，从腰缠转，或左或右，良久痛甚，则见于皮下，不妨乳食。其证先因
有疾表解未尽，遽尔下之太过，气虚寒搏，郁结而成。法宜益气理虚，用参苓白术散（不乳食）、沉香槟榔丸（癖）、
木香莪术丸（宿食）为治，或间投白芍药汤（疝）加人参、茯苓，水姜煎服。
癖痛治法详癖门
按∶ 瘕 癖四证，大同小异，治法亦无大分别，似不必琐琐作名，亦可也。

[Zeng] Jia tong (pain associated with abdominal masses) is caused by the accumulation of pathogenic factors over a long period. This results from the deficiency of both Ying (Nutritive Qi) and Wei (Defensive Qi). Externally, it involves contraction of Wind-Cold; internally, it stems from excessive damage to milk and food intake. After prolonged stagnation, digestion fails, causing pathogens to merge into the Yin aspect, forming "Yi" (a fixed mass), where Yin energy is static, leading to coagulation without movement; or merge into the Yang aspect, forming "Jia" (a mobile mass), which takes shape resembling objects and moves incessantly. If left untreated for a long time, it may develop into Pi Gan Ji (Spleen-related malnutrition and accumulation), or present as stone-like hard lumps between the two hypochondria, painful upon pressure but mild when untouched. Symptoms may include sallow complexion, emaciation, a hard and distended abdomen with visible cyanotic veins, coolness during the day and fever at night, irregular tidal fever, reduced appetite for milk and food, pica (craving for dirt), or loose stools. During pain episodes, the body may feel cold as ice. The treatment principle should be to regulate the Spleen and nourish the Stomach, using Xingpi San (Awakening the Spleen Powder) for Slow Convulsion, or Shenling Baizhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder) for anorexia. To resolve accumulations and treat Gan Ji, use Huapi Wan (Eliminating Accumulation Pill) for Pi (accumulated dampness/phlegm), Sanleng San (Sparganium Powder) for retained food, or Muxiang Ezhu Wan (Costus and Curcuma Pill) for retained food. For loose stools, use Meishi Zi Wan (Terminalia Chebula Pill) for diarrhea, or Chenxiang Binglang Wan (Aquilaria and Areca Nut Pill) for Pi accumulation. However, such accumulation diseases cannot be cured in seven doses; sequential regulation is required, and recovery will occur naturally over time.
[Zeng] Initially, there is a small, elongated lump inside the abdomen, hard as an arm, winding around from the waist, shifting left or right. After a while, pain intensifies, becoming visible subcutaneously, yet not interfering with feeding. This condition arises because the exterior syndrome was not fully resolved, and purgatives were used excessively, leading to Qi deficiency, Cold stagnation, and郁结 (depression and knotting). The treatment should focus on tonifying Qi and regulating deficiency, using Shenling Baizhu San (for anorexia), Chenxiang Binglang Wan (for Pi), or Muxiang Ezhu Wan (for retained food). Alternatively, administer Shaoyao Tang (Peony Decoction) intermittently for Shan (hernia), adding Renshen (Ginseng) and Fuling (Poria), decocted with water and fresh ginger.
For detailed treatment of Pi Tong (pain due to Pi), refer to the Pi section.
Commentary: Yi, Jia, and Pi syndromes are largely similar with minor differences, and their treatments are not significantly distinct. It may be unnecessary to create separate names for them.
