Just to tell you guys a little bit about my problem and where it all began. I'm 19 year old playing in an amateur football league trying to go D1. Ive been playing hockey and football since I was in 4th grade. Never really had any problems with my head or anything. My freshman year of football is when I had my first (of my knowledge) real concussion. I hit a kid and went blank, woke up 2 periods later standing on the side line and had no clue what had happened and nobody had tended to me or anything, just sat me out because I wasn't acting right. Then from then on I can name about 9 other incidents where after hitting somebody my bell is rung and I have a huge headache. And about 5 other ones where I have seen discoloration and cross eyed after a hit. Needless to say I've had a lot. But I don't want to give up sports.. I don't know if these are symptoms but I sometimes loose train of thought a lot more than I used to, will read a completely dif word than whats on the page, sometimes have a hard time talking, and sometimes I get depressed and moody for no reason. Please help me if its not concussions then what is it?!
