Has anyone else ever had a concussion. I had one about a 7-8 months ago. I have no real lasting effects from it, but now it's always seems to be on my mind a little when sparing. IT was a freak accident that caused it. And I have never had any problems like this before or after the one incident. I guess im just asking if anyone else has had one, how it affected them. And if they approach fighting, sparring differently. And are you truly worried about it happing easier a second time b/c you had one. If im being to vague just let me know, as a few questions.
