After traveling abroad, I suddenly became allergic to cold air. Chinese medicine and western medicine have been eaten for two months.

Hello, most people who are allergic to cold air have the reason of "disharmony between camp and health", and the lack of healthy qi can't resist the cold, so there will be symptoms such as skin allergy and acne.

Suggestion:

This paper puts forward a representative prescription for treating "cold allergy": the first prescription of Treatise on Febrile Diseases (Guizhi Decoction) is treated with Guizhi Decoction, which means taking Yupingfeng Powder at ordinary times to increase the body's ability to resist cold.
