三里发表现为肿胀呈牛眼状，位于膝眼下方，感觉寒冷且疼痛凝滞。此病由劳力损伤筋脉兼有胃热所致，肿胀颜色呈现青、黑、紫色，溃破后流出紫血和脓液。
【注】此证生于膝眼下三寸处，外侧前方两条筋之间的位置。初起时肿胀形状像牛眼，伴有拘挛急迫感和冷痛，这是由于劳力伤筋，加上胃热凝结而形成的。随后肿痛逐渐加重，颜色变为青黑色，溃破后流出紫血，接着流出稀薄的脓液。内治和外治的方法，都参照痈疽肿疡、溃疡章节中的方法。
腓发发生在大腿后侧的小腿肚部位，表现为怕冷、烦躁，由积热形成。如果肿痛并溃破出脓血为吉兆；如果漫肿平塌且流出清水则为凶兆。
【注】此证发生在腓部，即小腿肚。这是由于肾水不足，膀胱积热凝结而成，古方认为难以治愈。如果患处红肿高突、疼痛剧烈，溃破后流出正常脓液并夹杂血液，属于吉象，为顺证；如果漫肿平塌，颜色紫暗且疼痛，溃破后流出清水，属于凶象，为逆证。初期服用仙方活命饮，溃破后服用八珍汤。气血虚弱者，服用十全大补汤；下焦虚损者，用桂附地黄丸进行补益。外治法同痈疽溃疡章节。
黄鳅痈生在小腿肚旁边，疼痛、坚硬肿胀，形状像泥鳅一样长。由肝脾湿热引起，颜色微红，若溃破流出稠厚脓液为顺证，若流出败坏的浆液则为逆证。
【注】此证生在小腿肚内侧，疼痛且坚硬肿胀，长度有几寸，形状像泥鳅，颜色微红，这是由肝、脾两经的湿热凝结而成的。到了应期溃破并流出稠厚脓液的属于顺证；如果流出污水或败坏的浆液则属于逆证。初期服用五香流气饮，其次的内治和外治方法，都参照痈疽肿疡、溃疡章节。
Sanli Fa (Abscess at the Sanli Region) presents with swelling in the shape of an ox's eye, located below the knee eye, characterized by coldness and congealed pain. This condition is caused by injury to the sinews due to labor combined with Stomach Heat. The swelling appears blue-black or purple, and upon ulceration, it discharges purple blood and pus.
[Note] This syndrome occurs three cun below the knee eye, between the two tendons on the anterior aspect of the lateral side. Initially, the swelling resembles an ox's eye, accompanied by stiffness, urgency, and cold pain. It arises from injury to the sinews due to labor and the congealing of Stomach Heat. As the swelling and pain gradually increase, the color turns blue-black; upon ulceration, purple blood is discharged first, followed by thin pus. Both internal and external treatment methods follow those for abscesses and ulcers in the corresponding chapters.
Pi Fa (Abscess at the Pi Region) occurs in the calf muscle, presenting with aversion to cold, irritability, and accumulation of heat. Swelling with pain that ulcerates and discharges pus and blood is auspicious; diffuse swelling that is flat and discharges clear fluid is ominous.
[Note] This syndrome occurs in the Pi region, which refers to the calf muscle. It is caused by insufficient Kidney Water and the congealing of accumulated Heat in the Bladder. Ancient texts consider it incurable. If the area is red, high, swollen, painful, and upon ulceration discharges normal pus mixed with blood, it is auspicious and represents a favorable progression (Shun). If the swelling is diffuse and flat, dark purple, painful, and upon ulceration discharges clear fluid, it is ominous and represents an unfavorable progression (Ni). In the initial stage, administer Xianfang Huoming Yin (Immortal Life Elixir Decoction); after ulceration, administer Bazhen Tang (Eight-Treasure Decoction). For patients with Qi and Blood deficiency, administer Shiquan Dabu Tang (Ten Great Tonifying Decoction); for deficiency in the Lower Jiao, tonify with Guifu Dihuang Wan (Cinnamon Twig and Aconite Pill Rehmanniae). External treatment methods are the same as those for abscesses and ulcers.
Huangqiu Yong (Yellow Loach Carbuncle) occurs on the side of the calf, characterized by pain, induration, swelling, and a length resembling a loach. It is caused by Damp-Heat in the Liver and Spleen, appearing slightly red. Discharging thick pus upon ulceration indicates a favorable course (Shun), while discharging putrid serous fluid indicates an unfavorable course (Ni).
[Note] This syndrome occurs on the medial side of the calf, characterized by pain, induration, and swelling, several inches in length, resembling a loach, with a slightly red color. It is formed by the congealing of Damp-Heat in the Liver and Spleen meridians. Ulceration occurring at the appropriate time with the discharge of thick pus is considered favorable (Shun); discharge of turbid water or putrid serous fluid is considered unfavorable (Ni). In the initial stage, administer Wuxiang Liuqi Yin (Five-Aromatic Qi-Flowing Decoction). Subsequent internal and external treatment methods follow those for abscesses and ulcers in the corresponding chapters.
