痼发皆由外感生，伸缩动处每成形，漫肿无头寒热作，四肢沉重渴烦增。
【注】此证体虚之人，感受天地不正之厉气而生，非由内作也。多生于手足掌心，
或腰、腿、臀下伸缩动处，疼如痛风，而兼漫肿无头，其色淡红，憎寒发热，四肢沉重。
烦渴初起，宜服万灵丹发汗解表，肿仍不消，必欲作脓者，宜托里消毒散，兼琥珀蜡矾丸
间服；已溃者，按痈疽溃疡门治法。

痼发（一种外科疾病）皆由外感邪气引起，好发于肢体伸缩活动的部位并容易形成肿块。表现为漫肿无头、伴有寒热症状，四肢沉重且烦渴加重。
【注】此证多见于体质虚弱之人，因感受天地间不正的疫疠之气而发病，并非由体内因素产生。多生于手足掌心，或腰、腿、臀部等伸缩活动的部位。疼痛类似痛风，兼有漫肿无头，肤色淡红，憎寒发热，四肢沉重。初起时烦躁口渴，适宜服用万灵丹以发汗解表；若肿胀仍不消退，必然化脓者，适宜服用托里消毒散，并配合琥珀蜡矾丸交替服用；已经溃破者，按照痈疽溃疡门的治法处理。
瘭疽（一种外科疾病）本源于烟瘴之气，患处小如粟豆，大如梅李。初起时为红色斑点，随后变为黑色，导致筋骨腐烂，疼痛不止。
【注】此证又名蛇瘴，起源于四川、广东等烟瘴之地。初起为红点，继而变黑，形状小的如粟豆，大的如梅李，可在身体各处发生。疼痛剧烈，牵连心脏般持续不止，导致筋骨腐烂，溃破后流出的脓液像豆汁一样，今日擦拭干净，次日脓汁又充满，愈合后又复发。初起时适宜贴敷蟾酥饼；若出现寒热交作，适宜服用黍米寸金丹，或者夺命丹也可以；若红肿游走不定，使用离宫锭涂抹，并配合神灯照熏疗法。溃破后若脾虚、食少、呕吐者，服用补中益气汤加黄连、麦冬；若进补后无效，或流出稀薄污水、秽浊汁液的，属于逆证（预后不良）。
Gufa (a surgical disease) is entirely caused by external pathogenic factors, typically forming lumps at areas of limb flexion and extension. It presents with diffuse swelling without a distinct head, accompanied by chills and fever, heaviness in the four limbs, and increased irritability and thirst.
[Note] This condition occurs mostly in individuals with weak constitutions due to contracting abnormal epidemic qi from heaven and earth, rather than arising from internal causes. It often arises on the palms of hands and soles of feet, or at flexible areas such as the waist, legs, and buttocks. The pain resembles gout, accompanied by diffuse swelling without a head, pale red discoloration, aversion to cold with fever, and heaviness in the four limbs. At the initial stage, when there is irritability and thirst, it is appropriate to administer Wanling Dan (Ten Thousand Spirits Pill) to induce sweating and release the exterior. If the swelling does not subside and suppuration is inevitable, Tuoli Xiaodu San (Decoction for Supporting the Interior and Eliminating Toxins) should be administered, alternating with Hupo Lafan Wan (Amber and Alum Pill). For cases that have already ulcerated, treatment should follow the methods outlined in the Ulcerative Sores section.
Biaoju (a surgical disease) originates from miasma and pestilential vapors. The lesions are small like millet seeds or large as plums and apricots. Initially presenting as red spots, they subsequently turn black, leading to rotting of muscles and bones with ceaseless pain.
[Note] This condition is also known as Shezhang (Snake Miasma), originating from regions with miasma and pestilence such as Sichuan and Guangdong. It begins as red spots that turn black; the lesions vary in size from millet seeds to plums and can occur anywhere on the body. The pain is severe, unceasing, and feels as if it affects the heart, causing rotting of muscles and bones. Upon ulceration, the pus resembles bean curd dregs; even if cleaned today, the pus refills by the next day, and the condition recurs after healing. At the initial stage, applying Chansu Bing (Toad Venom Cake) is appropriate. If chills and fever alternate, Shumi Cunjindan (Millet-Inch Golden Pill) or Duoming Dan (Life-Rescuing Pill) may be taken. If redness and swelling wander unpredictably, apply Ligong Ding (Ligong Paste) and use Shendengzhao (Divine Lamp Illumination Therapy). After ulceration, if spleen deficiency manifests with poor appetite and vomiting, Buzhong Yiqi Tang (Decoction to Tonify the Middle and Augment Qi) with Huanglian (Coptis Rhizome) and Maidong (Ophiopogon Tuber) should be used. If tonification yields no response, or if thin, foul-smelling fluid discharges appear, this indicates a adverse prognosis (Ni syndrome).
