论曰香港脚缓弱者，由肾脏虚，风入其经，故筋弛纵而酸弱。内经谓缓风湿痹是也。古方
载苏氏论亦云，不肿而缓弱，行挛屈倒，渐至不仁，盖风湿毒瓦斯之感人，多不即觉；或因他
疾，乃始发动。初若不足畏，驯察其状，自膝至脚，已有不仁；或痹痛；或如虫喙；或足趾
及胫酸痛；或屈弱不能行。皆缓弱之证也。

论述说：香港脚（足部肿胀疼痛或痿软无力的病症）表现为缓弱（肌肉松弛无力），是由于肾脏虚弱，风邪侵入其经脉，导致筋脉弛纵而酸软无力。《内经》所说的“缓风湿痹”就是这种情况。古代医方中记载苏氏的论述也说，如果不肿而表现为缓弱，行走时拘挛屈曲甚至跌倒，逐渐发展到感觉迟钝麻木，这是因为风湿毒气侵袭人体，往往不会立即察觉；或者因为其他疾病诱发才发作。起初似乎不足为惧，但仔细考察其症状，从膝盖到脚部，已经出现麻木不仁；或者出现痹痛；或者像被虫咬一样刺痛；或者足趾和小腿酸痛；或者屈伸无力不能行走。这些都是缓弱的证候。

Discourse states: Hong Kong foot (a disease characterized by swelling, pain, or flaccidity of the lower limbs) presenting with flaccidity and weakness is caused by deficiency of the Kidney, where Wind pathogen invades its meridians, leading to laxity of tendons and acid-weakness. The *Neijing* refers to this as "Flaccid Damp-Wind Bi" (Bi syndrome due to damp-wind causing flaccidity). Ancient prescriptions record that Su Shi also stated: if there is no swelling but rather flaccidity and weakness, with spasmodic flexion during walking or even falling, gradually progressing to insensibility, it is because Damp-Wind toxic qi invading the human body often does not manifest immediately; or it may be triggered by other diseases. Initially, it may seem insignificant, but upon careful observation of the condition, from the knee down to the foot, there is already insensibility; or Bi pain; or a sensation like insect bites; or soreness and pain in the toes and shins; or weakness preventing movement. These are all signs of flaccidity and weakness.
