this explains a lot dynamo!!! i kid... i kid. sorry to hear about your continued problems. i had a mild concussion this past summer. who knows how many i might have had as a kid, tackle football with no gear every weekend probably left my head like that watermelon. anyway, i had some of the symptoms that you have mentioned here. albeit, probably a lot more mild than yours, the one very striking thing to me was also the personality changes. that's what was most disturbing to me. i just didn't feel like myself... and, in short, it was really bumming me out. inability to focus, headaches and irritability were pervasive for a few months. i'm still having 'off' days, but my symptoms have pretty much subsided 6 months after impact. suffice it to say... it's a truly awful feeling that i wouldn't wish on anyone. i hope your symptoms fade away. i also hope prongs can have his wear off, but it doesn't seem likely... sadly. people wonder why these guys make so much money to play a game. well, they're very often sacrificing their quality of life later in life. some might say that you couldn't pay them enough to take that deal.
