Mark,

Thanks for your reply.

Noted re tv and video games.

We're definitely steeling for the possibility of reduced activity for a longer stretch.

Heading isn't part of his soccer yet. I think they'd done one session on it & the coach is sensitive to potential of injury from doing so at an early age. It almost never comes up in games at this age - they don't have the coordination.

It's an active community (ski town in BC), so I'm hoping that the family doc has some prior experience with this. I've also got a few friends who are doctors and parents have kids the same age that will offer informal advice.

He's already sold on the merits of skiing over snowboarding. I'll ask the doctor about whether he should ski at all while low grade nausea persists. He's a very strong skier, so I imagine sticking to easy groomed runs would minimize chance of further injury, but I'm very hesitant to expose him at all ...
