DD was sent home from school today, she was absolutely fine this morning but apparently started complaining of being a bit hot and cold at break time. Then started to say she had a tummy ache a bit later so they called me. I gave her calpol although she didn't have a temp. However an hour after that her temp has shot up to 40 and she was complaining of a headache. Took her to GP who can't see any obvious cause, no redness in her ears or throat and nothing in her urine. We've been told if temp doesn't come down in an hour to take her to the hospital. Just trying to work out what kind of bugs are doing the rounds at the moment or if anyone has had similar with no obvious cause.
