<human>: The incident occurred over a year ago now when I was struck directly in the head by a person's full body (they were stage diving at a metal show, and I wasn't paying attention). I got tunnel vision from it and felt initially a little woozy, but after some fresh air I pretty comfortably watched the rest of the show.  
After this I walked back to where we were staying, slept, and then sat in a car for 13 hours the next day, all with discomfort but nothing too bad.  
For the following months I felt stiff, and experienced a bit of trouble looking up for awhile, which I foolishly did not get checked out, but it faded away and I have not felt any pain since.  
The reason I ask is because I just felt a little familiar pain in my neck and I've become paranoid. I have also been studying Shakespeare for the past 48 hours and it is likely that I am just getting sore from looking down at the book, up at the screen, etc.

Can you condense the text into a few key points?
<bot>: I'm paranoid that my neck is fractured or something from over a year ago and that I just grew used to it, thus feeling no symptoms, when really I could die at any moment.
