Generally speaking, it is difficult to distinguish hemp from wood completely, and hemp often coexists, so numbness of limbs has a certain relationship with deficiency of qi and blood. The main clinical symptom is skin numbness, which is also called "blood stasis" in Chinese medicine. Its pathogenesis lies in deficiency of camp and health, weakness of qi and blood, yin and yang, exogenous cold, stagnation of Yang Qi and poor blood circulation, so it is called blood stasis. This kind of joint pain is closely related to external factors, such as blowing hair immediately after sweating, sitting in the wetland, wading in the rain and so on. It will lead to the invasion of wind, cold and dampness into the meridians of the human body. These pathogens will stay at the joints after entering the human body, leading to the stagnation of qi and blood in the meridians and numbness of the skin.
