Suggest Remedy For A Rash In The Neck

Hi, may I answer your health queries right now ? Please type your query here...I have a rash on my neck. I have been taking tylenol the last couple days to cope with a fever. I have been taking it in the right dosage. However, I have developed a rash on my neck and legs. Is this normal? Should I be worried? Everything on the internet blows it out of proportion so I need to make sure its just a little reaction to the pill and it will be gone in a few days or so.
