My son has had a rash show up randomly, mostly all over his body in the last couple days.  He is fine one moment and the next this rash shows up. The area is red with light colored bumps and is hot to the touch. He says its a bit itchy too.  Benadryl seems to help a bit. I cant think of any food or anything in his environment that has changed other than what appeared to be few tiny bug/spider bites. What should I do?
