Ds has been getting head rushes a lot and occasionally blackout. Just getting out of the bath he blacked out, got up, blacked out 2 more times and banged his head hard. Says he is ok.
He says it wasn't a very hot bath, I tell him to eat a bit more, is it low blood sugar?
Any ideas if it could be more than this and I should be worried?
I am worried already of course. He's 17.
