So I had a mishap on the way to class today. I saw a car backing up into the street I was walking up, so I decided to step over a small ledge to get to class and get out of his way. However, i stumbled, slamming my elbow and my knee. It hurt like hell, and for some reason I had trouble breathing for a few minutes despite just having a few scrapes. What the hell happened? Was I in shock or something? Anybody know?
