初起时身体轻微恶寒发热，饮食正常，结块肿胀微红，疼痛不深达骨骼的属于顺证。病情发展后活动自如，结肿形成囊状，疼痛有定时，脓液容易形成的属于吉兆。溃破后脓液稠厚，肿胀消退，疼痛减轻，身体轻便，神志清醒睡眠安稳、无发热的属于吉兆。溃后元气容易恢复，饮食容易进补，肌肉容易长实，脓水容易干燥的属于吉兆。
初起时身体出现恶寒发热，漫肿且颜色发白，肢体牵强拘急，疼痛深达骨骼的属于险证。病情发展后活动不便，整条腿漫肿，不热不红，不能化脓的属于险证。溃破后脓水清稀，气味秽浊腥臭，肿痛不消，形体日渐消瘦的属于死证。溃后脾胃虚弱，饮食无味，口渴不止，嘴唇苍白皮肤干枯的属于死证。
初起时发热恶寒，身体拘急，腿脚肿痛，脉象浮紧的，宜用发散法治疗。病情发展后腿脚肿痛，皮色不变，上下通体肿胀的，宜散寒、温通经络。因寒热交替导致肿胀，颜色白而光亮，按压后凹陷不起的，宜健脾渗湿。身体无热但恶寒，脉象迟而涩，腿肿但不热的，宜养血、温通经络。中暑邪侵袭三阴经，脉象洪大而数，腿脚肿胀，口干大便燥结的，宜用泻下法。溃破后脓水清稀，饮食减少，形体消瘦的，宜补中益气、健运脾胃。溃后肿痛不减，脓水不止，虚热不退的，宜温中、滋养气血。痊愈后筋骨牵强，屈伸不便的，宜滋养气血、通利关节。
有一个男子，感受寒邪后发散未尽，大腿肿痛，脉象浮数而无力，这是风寒之邪未尽且体内正虚的缘故。用五积散去麻黄加牛膝，服用两剂，疼痛稍减；又用内托黄芪酒煎汤，服用四剂，全身肿胀全部消退。只有腿外侧结块一块未退，这是瘀血凝滞即将化脓的表现，用托里药等待脓熟后针刺排脓，再用十全大补汤收敛伤口。
有一个男子，因劳累受寒，每次发作腿痛，发作时伴有恶寒发热、呕吐，胸膈痞闷不想进食，这是因为气恼、饮食不节，损伤了脾胃，导致脾气亏虚，饮食不能运化痰湿停滞，中脘湿热下注流聚而成香港脚（足部肿痛）。服用开结导引丸两剂，排出停积的痰饮；又服用半夏佐经汤数剂，呕吐停止，膈间通畅，再用附子六物汤，数剂后症状消除且不复发。
有一位六十岁的老人，因房事过度导致肾虚，致使筋脉挛缩痹阻，脚膝无力，不能行走。外贴祛风逐湿膏，内服三因胜骏丸而痊愈。
有一个男子右腿肿痛两个多月。我说：“脓已经形成很久了，为什么不切开引流？”他说：“两位老医生共同诊治，都称内部消散没有脓，这脓到底是不是真的存在？这应该再请那两位老医生决定。”又说：“这一定没有脓。”但患者此时昏沉不醒，生命垂危。我强行切开，流出脓液约一盆，连续服用两剂独参汤后苏醒，后来用十全大补汤调理百日后才安定。
有一个男子在房事后感到阴部寒冷，大腿无形作痛，到了夜晚尤其严重，不能行走。医生用散寒除湿、消痰止痛的药治疗，他的疼痛反而加剧。诊察其脉象细涩而无力，这是气血不足，寒气乘虚而入的症状。应当用大防风汤，服用两剂疼痛立刻减轻；又服四剂，疾病痊愈安康。
有一个男子在暑月行房事后，对着风睡觉，导致寒气侵袭左腿，于是形成肿痛，寒热交替发作，胸膈痞闷不想进食。用保安万灵丹配合葱汤化服，洗浴发汗，以散发骨髓中的寒毒。后来用大防风汤去掉羌活，加入红花、破故纸温暖肾经，通行经络，肿痛逐渐消退，血脉逐渐调和，后来间断服用三因胜骏丸调理，两个月后痊愈。
有一个监生类似前述情况，房事后受寒，导致腿痛，我用暖肾经、温经络、散寒邪的药治疗。他认为见效慢，请内科医生诊治，甘服表散之剂，虽然外邪已散，但体内必然虚弱。又用小柴胡汤等药调理，导致虚热发作，口燥咽干，烦渴不已；又用知母石膏汤清其上焦，用防风、木瓜、威灵仙等剂攻其下焦，众人议论纷纷，杂药乱进，导致病情加重。再次请求诊治，此时患腿更加肿胀，形体缩小，这一定是死症。况且此症原本是从肾经受寒，非附子、破故纸不能通达关节；非羌活、防风、牛膝不能通行闭滞；非人参、白术、炙甘草不能使脾气运行到达四肢；非川芎、当归、白芍、熟地、红花不能养血活血。凡是病从虚而入的，先补其虚，后攻其病。况且治疗此症，不加温补反而用发散解肌，以治疗风寒有余的正法来治，不死还等什么？后果然死亡。众多医生误治，他才相信并服用我的药。
At the initial stage, if there is slight aversion to cold and fever, normal diet, a localized swelling that is slightly red, and pain that does not adhere to the bone, it is a favorable condition (Shun). If the condition progresses with free movement, the swelling forms a sac-like structure, pain occurs at specific times, and pus forms easily, it is an auspicious sign (Ji). After ulceration, if the pus is thick, swelling subsides, pain decreases, the body feels light, consciousness is clear, sleep is stable, and there is no fever, it is auspicious. If after ulceration, vital energy (Yuan Qi) recovers easily, diet improves, flesh becomes firm, and pus dries up easily, it is auspicious.
At the initial stage, if there is aversion to cold and fever, diffuse swelling with white color, limb stiffness and tension, and pain adhering to the bone, it is a dangerous condition (Xian). If the condition progresses with difficulty in movement, diffuse swelling of the entire leg, absence of heat and redness, and failure to form pus, it is dangerous. After ulceration, if the pus is thin and watery, has a foul and fishy odor, swelling and pain do not subside, and the body emaciates day by day, it is a fatal condition (Si). If after ulceration, the spleen and stomach are weak, food lacks taste, thirst is unquenchable, lips are pale, and skin is dry, it is fatal.
At the initial stage, if there is fever and aversion to cold, bodily stiffness, swelling and pain in the legs and feet, and a floating and tight pulse, dispersing methods should be used. If the condition progresses with swelling and pain in the legs and feet, unchanged skin color, and diffuse swelling from top to bottom, cold-dispersing and meridian-warming methods should be applied. If swelling is caused by alternating cold and heat, with white and bright color, and indentation remains after pressing (like mud), spleen-fortifying and dampness-draining methods are suitable. If the body has no heat but aversion to cold, with a slow and choppy pulse, and swollen but cool legs, blood-nourishing and meridian-warming methods are indicated. If summer-heat pathogen invades the Three Yin meridians, with a surging and rapid pulse, swollen legs and feet, dry mouth, and dry stool, purgative methods should be used. After ulceration, if pus is thin and watery, diet is reduced, and the body emaciates, middle-jiao tonification and spleen-stomach strengthening are appropriate. If after ulceration, swelling and pain persist, pus flows continuously, and deficiency heat does not recede, warming the middle and nourishing qi and blood are required. After recovery, if tendons and bones are stiff with limited flexion and extension, nourishing qi and blood and promoting joint mobility are suitable.
A man suffered from incomplete dispersion of cold pathogen, resulting in thigh swelling and pain, with a floating, rapid, and forceless pulse. This indicates residual wind-cold and internal deficiency. Wuji San (Five Accumulations Powder) without Mahuang (Ephedrae Herba) plus Niuxi (Achyranthis Bidentatae Radix) was administered for two doses, reducing pain slightly; then, Neituo Huangqi Decoction brewed with wine was given for four doses, resolving all swelling. However, a localized swelling remained on the lateral side of the leg, indicating stagnant blood about to suppurate. Internal-promoting medicine was used until pus matured, followed by needle drainage, and finally Shiquan Dabu Tang (Decoction for Complete Great Tonification) was used to heal the wound.
A man suffered from leg pain triggered by labor and cold exposure. Each episode involved aversion to cold, fever, vomiting, chest fullness, and anorexia. This was due to anger and irregular diet damaging the spleen and stomach, leading to spleen qi deficiency. Consequently, dietary essence failed to transform phlegm and stagnation, causing damp-heat in the Middle Jiao to flow downward into the lower limbs, resulting in Hong Kong Foot (Gouty Arthritis/Chronic Ulcerative Leg Condition). Kaie Daoyin Wan (Pill for Opening Knots and Guiding Flow) was taken for two doses to expel retained phlegm; Banxia Zuojing Tang (Banxia Meridian-Assisting Decoction) was taken for several doses to stop vomiting and clear the diaphragm; finally, Fuzi Liuwu Tang (Fuzi Six-Ingredient Decoction) was taken for several doses, eliminating symptoms and preventing recurrence.
A sixty-year-old man suffered from kidney deficiency due to excessive sexual activity, leading to tendon spasms, bi-syndrome contraction, weakness in the feet and knees, and inability to walk. External application of Qufeng Zhushi Gao (Wind-Expelling and Dampness-Removing Plaster) combined with internal administration of Sanyin Shengjun Wan (Sanyin Victory Steed Pill) resulted in recovery.
A man suffered from right leg swelling and pain for over two months. I stated: "The pus has formed long ago; why not incise it?" He replied: "Two senior physicians treated me together, both claiming internal resolution without pus. Is this pus real or not? I should ask them again." He added: "There must be no pus." However, the patient was comatose and critically ill. I forcibly incised him, draining approximately one basin of pus. Du Shen Tang (Single Ginseng Decoction) was administered consecutively for two doses, restoring consciousness. Subsequently, Shiquan Dabu Tang was used for conditioning for over a hundred days, leading to stability.
A man experienced genital coldness after intercourse, followed by formless pain in the thigh, worsening at night, and inability to walk. Physicians treated him with cold-dispersing, damp-draining, phlegm-resolving, and pain-relieving herbs, which exacerbated the pain. His pulse was fine, choppy, and forceless, indicating qi and blood insufficiency with cold pathogen invasion. Dafangfeng Tang (Great Saposhnikovia Decoction) was prescribed. Two doses significantly reduced pain; four more doses led to complete recovery.
A man slept facing the wind after sexual intercourse during summer, causing cold pathogen to invade the left leg, resulting in swelling and pain, alternating cold and heat, chest fullness, and anorexia. Bao'an Wanling Dan (Security Myriad Miracles Pill) dissolved in scallion decoction was taken, along with bathing to induce sweating, to disperse cold toxicity in the bone marrow. Later, Dafangfeng Tang without Qianghuo (Notopterygii Rhizoma et Radix) plus Honghua (Carthami Flos) and Pogu Zhi (Cibotii Rhizoma) was used to warm the kidney meridian and promote circulation. Swelling and pain gradually subsided, and blood vessels harmonized. Intermittent use of Sanyin Shengjun Wan for conditioning led to recovery in two months.
A student official suffered from leg pain similar to the previous case after cold exposure post-intercourse. I treated him with herbs to warm the kidney meridian, warm the meridians, and disperse cold. He considered this too slow and consulted an internal physician who prescribed surface-dispersing agents. Although external pathogens were dispersed, internal deficiency ensued. Xiao Chaihu Tang (Minor Bupleurum Decoction) and other medicines were used for conditioning, triggering deficiency heat, dry mouth and throat, and incessant irritability and thirst. Zhimu Shigao Tang (Anemarrhenae and Gypsum Decoction) was used to clear the upper jiao, while Fangfeng (Saposhnikoviae Radix), Mugua (Chaenomelis Fructus), and Weilingxian (Syneilesis Aconitifoliae Herba) were used to attack the lower jiao. Conflicting opinions led to indiscriminate medication, worsening the disease. Upon re-examination, the affected leg was more swollen and shrunken, indicating a fatal prognosis. Since the disease originated from cold invading the kidney meridian, only Fuzi (Aconiti Lateralis Radix Praeparata) and Pogu Zhi could open the joints; only Qianghuo, Fangfeng, and Niuxi could unblock stagnation; only Renshen (Ginseng Radix), Baizhu (Atractylodis Macrocephalae Rhizoma), and Zhi Gancao (Prepared Licorice Root) could transport spleen qi to the limbs; only Chuanxiong (Ligustici Chuanxiong Rhizoma), Danggui (Angelicae Sinensis Radix), Baishao (Paeoniae Radix Alba), Shudi (Rehmanniae Radix Preparata), and Honghua could nourish and invigorate blood. For diseases entering through deficiency, tonify deficiency first, then attack the pathogen. Treating this condition with surface-dispersing and muscle-releasing methods instead of warming and tonifying, applying the treatment for excess wind-cold, inevitably leads to death. The patient indeed died. Only after numerous physicians erred did he believe and take my prescription.
