Dear Doctor, I had a severe allergic reaction two weeks ago. I wasn t allergic to any food before and this was very suspicious. I had red bumps all over my body and was very itchy. I had to take a steroid shot and pills to calm down the reaction. After that my eyes started hearting me and when I went to the doctor he said I have pink eye.. I just want to ask you whether anyone can make me sick like that/poisoning me? It s just a thought came to my mind since I have never been allergic to any thing.....many thanks....
