人手足忽然皮浓涩，而圆短如茧者，谓之胼胝。此由血气沉行，不荣其表，故皮涩浓而
脚趾间生肉如刺，谓之肉刺。肉刺者，由着靴急小，趾相揩而生也。
肉裂者，皮急肉坼破也。由腠理虚，风邪乘之，与血气相冲击，随所击处而肉坼裂也。
尸脚者，脚跟坼破之名也，亦是冬时触犯寒气所以然。
又言脚踏死尸所卧地，亦令脚坼破。
病者，自膝以下至踝及趾，俱肿直是也。皆由血气虚弱，风邪伤之，经络痞涩
而成也。亦言江东诸山县人多病 ，云彼土有草名 草，人行误践触之，则令病
筋挛不得屈伸者，是筋急挛缩，不得伸也。筋得风热则弛纵，得风冷则挛急。
四肢痛无常处者，手足指节皆卒然而痛，不在一处。其痛处不肿，色亦不异，但肉里掣
痛，如锥刀所刺。由体虚受于风邪，风邪随气而行，气虚之时，邪气则胜，与正气交争相击
，痛随虚而生，故无常处也。
人的手足皮肤突然变得厚实粗糙，且圆形短小像茧一样，这叫做胼胝。这是由于气血沉滞运行，不能濡养体表，所以皮肤变得粗糙厚实，而在手足指甲边缘的皮肤剥起，这叫做逆胼（倒刺）。这是风邪侵入腠理，导致气血不和的缘故。
脚趾间长出像刺一样的肉赘，这叫做肉刺。肉刺的产生，是因为穿鞋过紧过小，脚趾相互摩擦而生成的。
肉裂，是指皮肤紧绷、肌肉开裂破损。这是由于腠理虚弱，风邪乘虚而入，与气血相互冲击，随着冲击的部位而导致肌肉开裂。
皲裂，是指肌肉破裂。指在科时（注：此处原文“科”疑为“冬”或特定季节之误，依文意理解为寒冷季节）触犯风寒，导致手足皮肤破裂，所以称为皲裂。
尸脚，是脚跟开裂破损的名称，这也是冬天触犯寒气所致。另一种说法是脚踏在死尸躺卧过的地面，也会导致脚跟开裂。
病（注：此处原文可能有缺字，结合语境指一种足部疾病），是指从膝盖以下到脚踝及脚趾，全部肿胀且僵硬挺直。这都是因为气血虚弱，风邪伤害了经络，导致经络阻滞涩滞而形成的。也有说法认为江东各县的人多患此病，说那里的土地有一种草叫[某]草，人走路不小心踩到触碰它，就会引发这种病。
筋挛不得屈伸，是指筋脉紧急拘挛收缩，无法伸展。筋脉遇到风热就会松弛纵缓，遇到风冷就会拘挛紧急。
四肢疼痛没有固定位置的，是指手足指节都突然感到疼痛，不在同一个地方。疼痛的地方不肿胀，颜色也没有异常，只是肌肉深处牵拉作痛，像被锥子刀子刺扎一样。这是因为身体虚弱受到风邪侵袭，风邪随着气机运行，当正气虚弱时，邪气就占上风，与正气交争相击，疼痛随着正气虚弱之处而产生，所以疼痛位置不固定。
言脚下有结块物，坚硬如石头，疼痛像被锥子刀子刺扎一样。这是由于肾经虚弱，风毒之气伤害了它，与气血相互冲击，所以疼痛并且结块坚硬不散。
这是由于脚趾先有疮口，泥土落入疮中，更加导致疮肿疼痛，也会使人出现憎寒壮热的症状。
The skin of the hands and feet suddenly becomes thick, rough, and round and short like a callus; this is called *piandi* (callus). This occurs because blood and qi circulate sluggishly and fail to nourish the exterior, causing the skin to become rough and thick. When the skin at the margins of the fingernails and toenails peels up, it is called *nizhou* (hangnail/reverse cuticle). This is due to wind pathogen invading the couli (interstices), leading to disharmony of blood and qi.
When flesh grows between the toes resembling a thorn, it is called *rouci* (fleshy spur/callus). The formation of fleshy spurs results from wearing tight or small shoes, causing the toes to rub against each other.
*Roulie* (skin fissure) refers to the skin being taut and the flesh cracking and breaking. This is caused by deficiency in the couli, allowing wind pathogen to invade and clash with blood and qi; the flesh cracks at the site of impact.
*Junlie* (chapped skin/fissure) refers to the rupture of muscle and skin. It is named so because exposure to wind and cold during cold seasons causes the skin of the hands and feet to crack.
*Shijiao* (cadaver foot/heel fissure) is the name for cracked and broken heels. This is also attributed to exposure to cold qi in winter. Another explanation states that stepping on ground where dead bodies have lain can also cause heel fissures.
*Bing* (a specific foot ailment) refers to swelling and rigid straightness from below the knee down to the ankle and toes. This is generally caused by deficiency of blood and qi, where wind pathogen injures the meridians, resulting in obstruction and stagnation. It is also said that people in various counties in Jiangdong often suffer from this disease; they claim there is a grass in that region called [Nameless Grass], and accidentally stepping on or touching it induces this condition.
*Jinluan* (tendon spasm) with inability to flex or extend refers to the tendons becoming tense, spasmodic, and contracted, preventing extension. Tendons become flaccid and relaxed when exposed to wind-heat, but become tense and contracted when exposed to wind-cold.
Pain in the four limbs without a fixed location refers to sudden pain in the joints of the fingers and toes, not confined to one spot. The painful area is not swollen, nor does the color change; rather, there is a pulling pain deep within the muscles, as if pierced by an awl or knife. This is due to bodily weakness allowing wind pathogen to invade. As wind pathogen moves with qi, when righteous qi is deficient, the pathogenic qi prevails. The clash between pathogenic qi and righteous qi generates pain at the site of deficiency, hence the pain has no fixed location.
*Genchu* (heel collapse/pain) refers to sudden pain in the heel that prevents bearing weight on the ground. The world calls this "heel collapse."
It describes a hard nodule under the sole, firm as stone, with pain akin to piercing by an awl or knife. This is caused by deficiency in the Kidney Meridian, where wind-toxic qi injures the area and clashes with blood and qi, resulting in pain and a hard, indurated mass that does not dissipate.
This occurs when there is initially a sore on the toe, and soil falls into the wound, exacerbating swelling and pain, and also inducing aversion to cold and high fever.
