This particular forum is not "expert" run. It's for average folks to ask questions, share experiences, get different perspectives. Also your question doesn't seem to be specifically related to heart disease.
I'm glad to hear the child is in the hospital. We, as common lay people, cannot begin to diagnose what's going on. We can offer comfort and encouragement. Hope you get some answers from the real experts.
the child is admitted in the hospital,i only want to know the most relevant diagnosis,it seems that no one cares about our questions,i mean the specialists,hence this site seems to be a waist of time in my opinion.thanks a lot.
Go to doctor. Whenever there's a fever with rash I worry about meningitis. And that can turn deadly quickly. Odds are it isn't but if it is, you can't wait and see.
