T.P.
My little guy just had a fever and mild cold that was accompanied by a rash on his chest and abdomen and behind his ears. It was light red, very small bumps, and did not seem to bother him at all (freaked me out, though). I called his doc and he said it was normal - sometimes when they run a fever or virus they can break out in a rash because of the infection or elevation in body temp. From my understanding (as a nurse) the strep rash is more hive-like and bothersome - an angry rash, if you will. And there is usually a bit more of a fever associated with strep.
Just keep in mind that the doctors and nurses are there to help and if you are worried or concerned just give them a call. They might be able to answer your questions over the phone.
Good luck!
