my 10month old daughter just woke up screaming like i have never heard before, i picked her up i noticed that she was masively sweating, but i took her temp and it was normal and when iput my arm under her bum to hold her and she screamed louder, so i went and changed her nappy, ( her last nappy change was at bath time and hour and a half ago), i noticed massive raised welts on the inside leg joins and on her bum and around her vagina, they weren t there an hour and a half ago and her face is flushed, she was farting alot as i soothed her.i lathered on the nappy rash cream and i dried the sweat from her hair so she wouldnt get a chill, and i gave her some panadol for the pain and rubed her back for the wind..(there is nothing new or different in her diet).. my question is what causes them welts to come up so harsh and quickly. and can you tell me if there are a few problems all at once or is there something wrong, should i take her to the hospital
