有人问：大腿和足部生出数个肿块，肿痛日久，溃烂不止，该怎么办？回答说：这病名叫瓜藤缠，归属于足太阳经，是由于脏腑湿热之邪，流注于下部所致。治疗宜用防风通圣散，加入槟榔、牛膝、防己为主方。
有人问：小腿之间生疮，形状像牛眼，颜色或紫或黑，脓水淋漓不断，结痂处随即又溃烂，久不愈合，该怎么办？回答说：这病名叫湿毒流注，多因暴风疾雨侵袭，寒湿暑气侵入腠理（皮肤纹理及肌肉间隙）而成。适宜服用防风通圣散，加入木瓜、牛膝、防己等药；或者使用当归拈痛汤，加入牛膝。
有人问：脚膝间脓水不绝，连年不愈，该怎么办？回答说：这病名叫下注疮，也叫湿毒疮。是因为脾胃湿热下注，导致肌肉失去知觉而形成的疮疡。在经络归属上，外部属于足太阳经、足少阳经；内部属于足厥阴肝经、足太阴脾经。适宜服用防风通圣散，加入木瓜、防己、牛膝等药；外用祛风类汤药清洗患处，并用女贞叶制成的膏药贴敷。
《灵枢》说：发于内踝的疮疡，名叫走缓。其症状是痈肿颜色不变，多次针刺其输穴以停止寒热发作，不会死亡。
有人问：足内侧生疽，该怎么办？回答说：这病名叫鞋带痈，是由于寒湿停滞于足阳明胃经，并与足厥阴肝经相互作用，导致血行涩滞、气机阻塞所致。初期适宜隔蒜灸治疗，并服用流气饮，加入牛膝、木瓜、防己。体质壮实者，可用一粒金丹攻下排毒。年老体弱者，则用十全大补汤、内托黄芪柴胡汤为主方。
有人问：足外踝生疽，该怎么办？回答说：这病名叫脚拐毒。归属于少阳胆经、足太阳膀胱经，由湿热下注引起。适宜选用内托羌活汤、黄连消毒散、内托复煎散服用；胜金丹、乌金散、紫金丹也都可以使用。
有人问：小腿生疽，溃烂严重，久不愈合，腐烂出骨，该怎么办？回答说：这病名叫多骨疽，也叫剩骨，又名朽骨。这是因为毒瓦斯壅盛，凝结形成此骨，并非正常的骨骼。适宜服用胜金丹、十全大补汤加牛膝、防己，以及紫金丹、乌金散、人参养荣汤加木瓜、牛膝、防己，交替服用。此疽是因为在溃烂之前，补益药物使用过度，导致毒邪凝结而不能消散，因此适宜传授仙纸黄龙膏贴敷患处。
A question was asked: "What if several nodules appear on the thigh and leg, causing swelling and pain for a long time, with persistent ulceration?" The answer is: This condition is named *Gua Teng Chan* (Climbing Vine Entanglement), belonging to the Foot-Taiyang Channel. It is caused by damp-heat in the zang-fu organs flowing downward to the lower part of the body. Treatment should primarily use *Fang Feng Tong Sheng San* (Saposhnikovia Decoction for Unimpeded Circulation) with added Areca Seed (*Arecae Semen*), Achyranthes Root (*Achyranthis Bidentatae Radix*), and Stephania Root (*Stephaniae Tetrandrae Radix*).
Another question was asked: "What if sores appear between the shins, resembling ox eyes, with colors ranging from purple to black, oozing pus continuously, where scabs form only to ulcerate again, failing to heal for a long time?" The answer is: This condition is named *Shi Du Liu Zhu* (Damp-Toxin Flowing Accumulation). It arises from invasion by cold-dampness and summerheat due to exposure to violent winds, heavy rain, or other climatic factors penetrating the *Cou Li* (interstices of skin and muscles). It is advisable to take *Fang Feng Tong Sheng San* with added Quince Fruit (*Chaenomelis Fructus*), Achyranthes Root, and Stephania Root; or alternatively, *Dang Gui Nian Tong Tang* (Angelica Decoction for Relieving Pain) with added Achyranthes Root.
Another question was asked: "What if there is continuous discharge of pus from the feet and knees, persisting for years without healing?" The answer is: This condition is named *Xia Zhu Chuang* (Lower-Falling Sore), also called *Shi Du Chuang* (Damp-Toxin Sore). It results from damp-heat in the spleen and stomach flowing downward, causing the muscles to lose sensation and form sores. Externally, it involves the Foot-Taiyang and Foot-Shaoyang channels; internally, it involves the Foot-Jueyin Liver channel and Foot-Taiyin Spleen channel. One should take *Fang Feng Tong Sheng San* with added Quince Fruit, Stephania Root, and Achyranthes Root. Externally, wash with wind-dispelling herbal decoctions and apply patches made from *Nv Zhen Ye* (Ligustrum Leaf).
The *Ling Shu* states: "Sores arising at the inner ankle are named *Zou Huan*. Their appearance shows no change in color of the abscess; repeatedly needling their Shu points to halt chills and fever ensures survival."
Another question was asked: "What if a carbuncle appears on the inner aspect of the foot?" The answer is: This condition is named *Xie Dai Yong* (Shoelace Carbuncle). It is caused by cold-dampness stagnating in the Foot-Yangming Stomach channel, interacting with the Foot-Jueyin Liver channel, leading to sluggish blood flow and obstructed qi. Initially, moxibustion with garlic slices is suitable, along with taking *Liu Qi Yin* (Flowing-Qi Drink) with added Achyranthes Root, Quince Fruit, and Stephania Root. For robust individuals, *Yi Li Jin Dan* (One-Pill Golden Elixir) can be used to purge the pathogen. For the elderly or weak, *Shi Quan Da Bu Tang* (Decoction for Great Tonification of All Ten Powers) and *Nei Tuo Huang Qi Chai Hu Tang* (Internal-Supporting Astragalus and Bupleurum Decoction) should be used as primary formulas.
Another question was asked: "What if a carbuncle appears on the outer ankle?" The answer is: This condition is named *Jiao Guai Du* (Ankle Deformity Toxin). It belongs to the Shaoyang Gallbladder channel and the Foot-Taiyang Bladder channel, caused by damp-heat flowing downward. Suitable treatments include selecting *Nei Tuo Qiang Huo Tang* (Internal-Supporting Notopterygium Decoction), *Huang Lian Xiao Du San* (Coptis Decoction for Eliminating Toxins), or *Nei Tuo Fu Jian San* (Internal-Supporting Re-decocted Powder); *Sheng Jin Dan* (Life-Generating Elixir), *Wu Jin San* (Black Gold Powder), and *Zi Jin Dan* (Purple Gold Elixir) are all applicable.
Another question was asked: "What if a carbuncle on the shin becomes severely ulcerated, fails to heal for a long time, and discharges bone fragments?" The answer is: This condition is named *Duo Gu Ju* (Multiple-Bone Abscess), also known as *Sheng Gu* (Remaining Bone) or *Xiu Gu* (Rotting Bone). This occurs because toxic vapors are excessive and condense to form this bone structure, which is not normal bone. It is advisable to take *Sheng Jin Dan*, *Shi Quan Da Bu Tang* with added Achyranthes Root and Stephania Root, alternating with *Zi Jin Dan*, *Wu Jin San*, and *Ren Shen Yang Rong Tang* (Ginseng Decoction for Nourishing Young Spirit) with added Quince Fruit, Achyranthes Root, and Stephania Root. This abscess occurred because tonifying agents were overused before ulceration, causing toxins to consolidate rather than dissipate. Therefore, it is recommended to apply *Xian Zhi Huang Long Gao* (Immortal Paper Yellow Dragon Ointment).
