My 8yr old daughter became I'll quite suddenly yesterday, she complained of a sore head, and when I checked she had a temp of 38.4°c I gave the usual medication and she fell a sleep, I thought it's just a virus. She woke a few times during the night complaining of this sore head and her temp went up to 39.1°c, I managed to get it back down. Today she has constantly complained of this sore head and sore throat and feeling sick, she has been sick once, not eating but taking sips of water, shes in bed and again has woken up twice with a sore head to the point shes crying. Is this likely to be just a virus? Or should I be more calling nhs?
