I'm allergic to pollen. My frined's allergic to shrimps. My friend's kids are allergic to dust.
いろいろアレルギーありますよね
What's happened when you are allergic? アレルギーが出ると、どうなるの? You are going to sneeze. You can get hives.
hivesって何だろう… :a condition in which someone's skin swells and become red, usually because they're allergic to something.
湿疹のような感じ? でしょうか。 rash: an area of red spots on a person's skin, caused by an illness or a reaction to sth. I come out in a rash(=a rash appears on my skin) if I eat chocolate.
rash よりはジンマシンみたいにふくれて赤くなるという感じでしょうか。
When I was a child, I had got hives if I ate fish sausages. 子供の頃、魚肉ソーセージを食べたらじんましんが出てました。
