On Friday afternoon at 4 p.m. I received a very hard hit to the side of my head while playing basketball. I've had a very light lingering headache since, and some trouble focusing on one thing, mentally, for very long. I have two practices on monday and a game on tuesday. Should I miss the practices? Should I miss both the practices and the game? I didn't black out during the hit and the physical trainer at the school I was playing at when the hit happened didn't suspect that I had a concussion. Any thoughts? My mom doesn't want to take me to the doctor so I need another opinion.
