The ride was pretty rough with a lot of potholes, it just didn't affect me as much as other events have. I was in bed Friday evening after the restaurant through Wed.

I doubt it was a concussion. Can you think of any things that might be causing the symptoms to flare up again? Like you said it was only for a few seconds. It's hard to believe it would have such a dramatic effect.

Good luck with the semester! I know how much anxiety it can cause. Have you thought about taking another semester off because of your increased symptoms? It might not be the worst idea. I know that I tried to push myself too hard this semester and am going to have to withdraw and lose some tuition.
