I was considered by myself and my peers to be a pretty good math student before my concussion and hoped to pursue a math-based career later on in my life. However after my concussion, I have begun to question my mathematical abilites and wonder if they will ever be up to par again. I suffered my concussion by getting hit in the head with a baseball and it was pretty mild. However about five weeks later, I have been hit in the head with a basketball twice since the event; once when my friend lightly passed to me and I wasn't looking; and the second time he tried to fake throw the ball at my head and it slipped. (is this sub-concussive force), would this cause permanent damage? Have I screwed myself in my pursuit of math? I really hope this isn't too bad I love math and want to pursue it.
