It is possible that I am in the same situation. I used to eat everything, but now crabs don't itch, and once I went hiking, I was allergic to raw sumac. The doctor said that I was allergic to raw sumac every day when I was a child, and now I am so weak.

Perhaps it has something to do with the current environmental changes and the changes in our diet, so physical changes are inevitable.

Just a few days ago, I was allergic to silkworm chrysalis. My symptoms are that my nose, eyebrows and ears are super red, especially my ears are red. I feel like a mutant in a science fiction movie. I also have some rubella-like particles on me. I was so hot that I fainted.

Advise the landlord not to touch allergens in the future, and then pay attention to exercise and diet. It's a little difficult to change the environment or something.
