question: My four year old got sick Thursday morning at about 2am. He puked about 5-6 times and had a fever until seeming to be all better at about 7pm Thursday evening. I took him to school Friday morning and then received a call that he had a rash all over his body at about 1pm. The rash isn t itchy and he doesn t seem to even notice it. I m assuming its not contagious because I haven t caught it. Any idea s on what this may be or any treatments for it? I gave him children s Benadryl about 45 mins ago and it doesn t seem to have done anything.
