Chinese medicine believes that sweaty and cold calves are mostly related to qi stagnation and blood stasis, yang qi deficiency and other factors. 1. Qi stagnation and blood stasis: Qi stagnation and blood stasis refers to the situation in which blood flow is stagnant due to the stagnation of qi for a long period of time. Due to the stagnation of qi and blood in the meridians and blood lead to the meridian qi, blood can not be conducted to the calf, the loss of local skin warmth can lead to cold skin, the coupling of the skin (pores) is not moistened, the opening and closing of the disorder, which further leads to the leakage of fluids, the calf sweating. 2. Yang Qi deficiency: Yang Qi deficiency refers to the lack of body Yang Qi, Yang Qi warming and promoting the dysfunction of the situation. Due to the malfunction of the warming function of yang qi, it will lead to cold extremities, and then because yang qi has the role of fluid retention, yang qi deficiency, fluid can not be normal retention, so there will be the performance of the calf sweat. Calf sweat from the cool patients, it is recommended to go to a regular hospital, under the guidance of a professional physician to identify the treatment.
