《伤寒论·辨痉湿暍脉证》
问：风湿之邪相合，引起周身疼痛，依照治疗法则，应当发汗驱邪，汗出邪散则病可痊愈。但正遇到天阴下雨不止，医生说可以发汗，发了汗病却不愈，这是什么原因呢?
问曰：风湿相搏，一身尽疼痛，法当汗出而解，值天阴雨不止，医云：此可发汗，汗之病不愈者，何也？
Question: The evils of wind and dampness are combined to cause pain all over the body. According to the treatment rules, sweating should be used to expel evil, and the disease can be cured when sweat comes out. However, when it rains all the time, the doctor says that it can be sweated, but the disease is not cured after sweating. What is the reason?
