It's hot recently, and my body itches. I get pimples when I scratch. What happened?

It should be a wind-sensitive rash, medically called measles, which is mostly caused by skin allergies. It is recommended to take some anti-allergic drugs (such as Xi Simin, etc. ) Don't bathe in water that is too hot or too cold, don't eat irritating food, and don't wash clothes and sheets. The problem is not big. This can happen to everyone.
