Rash...

Caitlin

I brought my 8 month old to the Dr yesterday due to rash and fever. They said it was probably viral he we'd have to wait it out. He had little red dot all over. The ones on his belly are gone, but he has this on his arm and bottom and thighs. They are raised now. If they are still raised and there tomorrow, I plan to call in to ask about it, but any advise otherwise? What do you think this could be? Or still part of his rash from what he was seen for before? They weren't raised before and are now.
