If you're still experiencing symptoms then don't push yourself it's still too early. Your brain needs time to heal after a TBI and audio/visual overstimulation can be as bad as strenuous physical exertion in not allow your brain to fully recover.

Most concussions will resolve and there will be no long term ill effects IF properly diagnosed and treated. The real tragedy is when you push yourself too hard early after a TBI (either because you didn't recognize the symptoms, or though that you could ignore them) and that leads to long term problems that are much harder to resolve.

We've learned from the sad experiences of other student athletes who have paid too a high price for lack of understanding of TBI. Better to sit out a game, then to sit out your life.

The really sad part is that the guideline ARE there, it's just that too many are unaware. Educating yourself as you are doing is the best approach!

Good luck and best wishes for a full recovery!
