question: My 14 year old daughter has a rash on her legs only. One is above her knee on her right leg. The size of a silver dollar.  Then ten inches above that are three, a few inches from each other, and the size of a nickel. On her left leg she has a rash on her thigh that looks more like a map. It is growing more each day, and each place is hot to touch, and betting redder.. Kind of mean looking. Have you ever heard of such. I have spent a long time researching. We haven't changed washing detergent, nor soap. She is alergic to red dye, and recently drank a lot of grape drink. This is day 4 of having. It is itching really badly. But if she scratches it makes it itch worse.
