Gilbert,

I would not be concerned about seeing your GP. He already gave you bad advice.

i.e. Go snowboarding so you can develop better balance. Not much different than, Bang you head against the wall to develop more tolerance for impacts.

Drod,

There is no value in asking how Gilbert recovered. As we have noted many times on NT, If you have seen one head injury, you have seen ONE head injury.

They are all different. The only standard is they all require quiet rest and good nutrition and behavior modifications.
