Hi, my daughter (7) has a red rash covering her entire butt area, and it seems to be movinh down the back of her thighs.. its just a red rash, no itch but fevered to the touch.. she feels fine otherwise but just keeps saying her butt is very hot.. my 9 yr old had fifth disease about a month ago, could it possibly be fifth disease?? I'm 15 weeks pregnant and I know if it is, it could harm my baby, so I really need help with this please.. thankyou in advance for your opinion and medical advice.. :-)
