How long ago was the original hit? 2 months or so?
Most likely you are much too early to worry about long term issues..
I'd say slow down on activities for awhile, slowly add them back as tolerated, avoid worrying as that doesn't help anything & don't put yourself in a situation where you might get more hits/knocks..

Side of head baseball hit may have misaligned your c1 c2..
any idea on how fast the ball was moving?
softball, hard ball - lobbed or fast pitch
ball sent by a person or machine?
