If she isnt drinking anything she could get (or already be) dehydrated, she may need iv fluids to be able to rehydrate herself. Have you tried alternating tylonol (sp?) and ibprophen or motrin every three hours for the fever, i remember my son when he was smaller ran a fever like that (not for that long of a period though), he had to be admitted to the hospital, he had pnemonia (sp?), and that is what they did for the fever, and it broke. My oldest boy got thrush alot, it was alway like a white yellow color and stinks, and a little hard to get off, they gave him meds, but they also got wet gauze or a wet wash cloth (with warm water) and rubbed it around his mouth to get some of it off (at least 2-3 times a day). But I would def. take her back to the ER ASAP, if you dont like the dr. (or what he/she has to say) you could always ask to speak to another or demand that she get admitted, i have done this before, because my son was sick and they couldnt figure out a "quick" answer ended up that he had kidney problems, it is your right to MAKE them do something, even if you have to "throw a fit" to get it done. I hope this helps ya any. Good Luck and I hope she gets better, I will be praying for her.
