Long time lurker, first time poster.

I had a moment the other day where I went over a small bump on a motorbike and my helmet went up and down. It didn't seem to be much at the time although the next day, it felt like I was back to square one.

All of the symptoms I had from a concussion sustained three months ago returned.

Things like inability to think straight or inability think about complicated tasks, That 'fog' that I experienced for the first two weeks after a concussion returned.

Is it possible that I sustained another concussion? How do you guys deal with ultra-sensitivity everyday? I feel fragile now and have got it in my mind that I can't do anything that may risk another concussion.
