Whenever the weather gets cold or wet and windy, red pimples appear on my body. How come...

Let me talk about my personal views on the first question. In recent years, I have also had this problem. As long as you suddenly feel "hot", such as doing manual labor suddenly, or entering a room with high temperature, as long as the temperature difference is large, you will be fidgety, itchy and very painful. I have seen many doctors, including Chinese medicine practitioners and western medicine practitioners, and even went to a chronic disease hospital for examination, but I have not found out the reason or diagnosed it. Most doctors will tell you: allergies. After eating all kinds of medicines, I found that two kinds of medicines have better effects: one is "Shidi" produced by Qilu Pharmaceutical Factory; Second, there is a kind called "XXX hydrochloride", and the last few words have been forgotten. sorry Take it when you get sick. After eating for several months, the symptoms are obviously relieved, and they will be committed, but the frequency is greatly reduced. Family statement, for reference only.
