senile foot chilliness，belong to the category of “arthralgia syndrome”. According to the analysis of traditional Chinese medicine, cold is a yin evil, and its nature is induced, which is the most likely to hurt yang, leading to poor qi and blood, and pain when it is blocked. Exogenous wind, cold, humidity and heat are related to the deficiency of healthy qi in human body. For example, some young people who don't pay attention to keeping warm often expose their legs to the cold environment, so that their legs are attacked by wind, cold and moisture, and they may suffer from senile foot chilliness.
老寒腿，属于“痹症”的范畴，从中医来分析，寒为阴邪，其性收引，最易伤阳，导致气血不畅，不通则痛。外感风、寒、湿、热之邪及人体正气不足有关，比如有些不注意保暖的年轻人常常把腿部暴露在寒冷的环境中，使腿部受到风寒、湿气的侵袭，就有可能患上老寒腿。
