Tell me about allergies that make you desperate.

Some people are allergic to peanuts and caffeine. Some allergies are congenital, while others are acquired. A friend of mine is a sports student and often participates in marathons. After the game, he got dysentery and was allergic to oil. As long as a lot of oil is added to the dish, he will have diarrhea. This is the day after tomorrow. Another friend is allergic to cold air. Every time it suddenly turns cold in winter, many small pimples appear on his body, which is very itchy. My sister is allergic to new clothes, and she gets pimples every time she buys new clothes. These are all born.
