DD had a sore throat yesterday, and then violent vomiting even when drinking water. High temp which came down (a bit) with Calpol.
Today her temp is down to 37.5 (not given calpol today), she didn't vomit in the night despite having sips of water, but she says her tummy still hurts a lot.
Even though her temp is down her cheeks are now very flushed and hot to touch.
The skin on her cheeks have I think a very faint rash (slightly raised). I thought she had the same thing on her bum but now not so sure 
About 4-5 days ago she had a reddish rash on both her hands and wrists, which she complained was itchy. This has now stopped itching and it's very dry. I originally thought it was eczema (although she doesn't normally suffer from it but has dry skin).
Now I'm wondering whether this is related to this current illness.
If it was scarletina/scarlet fever, would he temp have gone down?
Her tongue is also quite white
TIA
