I think the answer you're going to get here, from ANYONE, but potentially from KP2001, our resident military flight surgeon is:
Maybe.
Every individual is viewed independently...and each persons medical history is evaluated on its own. Nobody here can tell you definitively, at least, I don't think they can (KP, tell me if I'm wrong) from just that simple question.
Now...if you said: "I'm 17, have had 23 concussions from sports injuries..." then perhaps that might set off alarm bells, but again; ONLY a DODMERB official can tell you specifics to your case. There are some things listed in the DODMERB regulation that say "yes or no" but the vast majority of things...require individual evaluation.
