〔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

[Zeng] "Jia" pain is caused by long-standing accumulation, resulting from the deficiency of both Ying (Nutritive Qi) and Wei (Defensive Qi). Externally, it contracts Wind-Cold; internally, it suffers excessive damage from milk and food. After prolonged stagnation, digestion fails, so pathogens merge into the Yin aspect to form "Yi". Yin is characterized by stillness, coagulating without movement. Pathogens merging into the Yang aspect form "Jia", taking shape resembling objects, moving ceaselessly. If untreated for a long time, it may develop into Spleen Gan Accumulation, or lumps like stones may appear between the two hypochondria, painful upon pressure but mild when untouched. Symptoms may include sallow complexion, emaciation, hard and distended abdomen with visible blue veins, daytime coolness and nighttime fever, irregular tidal fever, reduced intake of milk and food, and pica (craving dirt). Or there may be loose diarrhea, with the body feeling cold as ice during pain episodes. The treatment method should regulate the Spleen and nourish the Stomach, using Xingpi San (for Slow Convulsion) and Shenling Baizhu San (for anorexia). To resolve accumulation and treat Gan syndrome, use Huapi Wan (for Pi accumulation), Sanleng San (for retained food), and Muxiang Ezhu Wan (for retained food). For treating loose diarrhea, use Meishi Zi Wan (for diarrhea) and Chenxiang Binglang Wan (for Pi accumulation). However, this disease of stagnation cannot be cured in seven doses; sequential regulation is required, and it will naturally recover 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 of a previous illness was not fully resolved, leading to premature and excessive purgation. This results in Qi deficiency, Cold binding, and郁结 (depression and accumulation). The treatment method should tonify Qi and address deficiency, using Shenling Baizhu San (for anorexia), Chenxiang Binglang Wan (for Pi), and Muxiang Ezhu Wan (for retained food). Alternatively, administer Shaoyao Tang intermittently (for Hernia) with added Renshen (Ginseng) and Fuling (Poria), decocted with water and fresh ginger.
For the treatment methods of Pi pain, see the Pi section.
Note: Yi, Jia, and Pi syndromes are largely similar with minor differences, and their treatments are not significantly distinct. It seems unnecessary to create separate names for them trivially.
The treatment for testicular hernia and unilateral descent is found in the Yin Swelling section.
The treatment for Cold Hernia is found in the Hernia section.
