My daughter had been getting some type of skin rash that last a few minutes firts the area fills hot then there is a rash like poison ivy and vanish?
Sounds like hives. Rash that comes and goes so quickly is most likely urticaria or hives. Is it itchy? Hives are usually itchy. The rash may develops without any provocation. Sometimes stress or emotional change triggers hives. If it is very bothersome, you should take her to a doctor and have him (her) prescribe medicine. If it accompanies wheezing, swelling of lips, tongue, or breathing problem, take her to er.
