DS (9yo) has complained for a few days of a belly ache, has generally not been himself - tired, sleeping in (terrible sleeper generally), slow on his feet. No signs of anything other than saying it was sore.
Picked him up from school and he's like a walking zombie, pale and very quiet and compliant (very unusual!). He's complained terribly of this abdominal pain on the lower left side - slight prod elicits a big reaction.
We came home and well he's got the runs big time (liquid sorry), slight fever of 37.8, he's still pale and quieter than normal. No vomiting (I hope it stays that way).
I'm assuming it's some sort of gastro bug although I have no idea from where he picked it up but the abdominal pain has me slightly questioning if I need to keep an eye on him. Are bigger kids a dehydration risk? He only drinks water and we are trying to make him do it. Any thoughts?
