everyone,
My friend has a little girl that is almost 3. She developed a rash about a month ago that lasted 1-2weeks. The rash looked like lots of little bites all over her skin and was very itchy. They took her to the doc (not their usual one) and he said he had no idea. So they tried some of her food as she seems to be allergic to a few different types of food. Anyway after a week or 2 it cleared up with the help of some excema cream.

Now a month later it has flared up again and is about a hundred times worse. First time it was mainly her legs, feet and belly. This time its her whole body. They have taken her to the docs again (this time their regular doc) and he has no idea either. He thinks possible allergic reaction to something but its just sooo horrible I was hoping someone might know something. It looks like a heat rash underneath or look red, inflamed goose bumps all over and then on top of that it looks like insect bites that she has scratched at and they have become lesions. Some of them look a little pussie too. They have 6 kids and not one of them has anything like it even her sister that sleeps in the same room has not a bite on her.

So if anyone has any idea PLEASE Any suggestions would be greatly appreciated.
P.S: I have also posted in the medical conditions but thought I might get more advice over here as maybe more ppl look at this forum.
