My DS1 who is 13 1/2 came home from school Tues afternoon, pale, sweaty and feeling sick. Expecting usual few hours throwing up and then back to school today. However, he hasn't been sick, doesn't have a temp, is eating small amounts of bland food which makes him feel sick again - spending a lot of time looking down the loo...- and generally looks grim, pale, black sunken eyes, achy and tired. He is drinking water so shouldn't be dehydrated but really isn't well. I can't work out whether to let it go for a bit longer or see the GP, I suspect it is just a question of wait and see, but hate seeing him so miserable and being unable to help. He isn't a shirker, and is generally well, and there's no particular bug going round school (and none of us have anything yet?) Any suggestions - what to feed, what to do? Thanx
