My six year old daughter woke up with a rash on her face and chest that has now spread to her arms, legs, and butt. It is raised a bit off the skin. She has no fever, no other symptoms. I had thought that perhaps she was alergic to something, but I would have thought that it would have went away by now. It has been two days. She is not bothered by it at all. Sometimes the color is a bright vivid red, and sometimes it seems to have almost disappeared. Any one have a clue?? Any advice??? HELP
