My Ds is just getting over this type of thing.
He came home from school last Wednesday, complaining of a headache and feeling achey, I just put it down to tiredness( he's in 4+). By Thursday morning he's got a high temp and flu like symptoms, and just laying on the sofa all day.There have been a few cases of chicken pox in his class so thought that maybe he was coming down with that.
Saturday morning he seemed a lot brighter and their Dad came to take DD and Ds out for lunch.
All was Ok till Sunday afternoon when his temp rocketed again and all his symptoms were back.
Took him to Docs Monday morning, and couldn't find anything wrong with him , and put it down to a virus.
He's slowly getting better, his temperatures gone and he's a lot brighter, so hopefully he'll be back at school tomorrow.
DD also ended up up being off this week as she woke up with Tonsillitus on Monday morning,but should also be able to go back tomorrow.
