Monday I was working making concrete test cylinders. I had a wheelbarrow will probably about 130lbs of concrete in it. Well, as I was moving it, the wheel got stuck in the sand and the whole thing started to pivot; I tried to keep it upright with no luck, and my left leg locked, jammed into the ground and buckled, leaving my on my back with my leg bent backwards underneath me and a big pile on concrete on the ground. Everyday since my left knee has been hurting and making it difficult to go up and down all the stairs at school. Now my ankle, shin and thigh have started hurting, even when I'm resting. I know my gait is a little off, but I can't imagine that's the only thing making my leg hurt.
