Limp

I have a bad ankle. My right ankle had some critical ligament rupture about six years ago. So every so often I will turn my ankle on seemingly nothing at all. I'm just walking along, and a tiny crack in the sidewalk will make me fall over. Just this morning, a pencil on the floor in my office put me on the ground, in a great deal of pain. Shortly after, a warm flood of endorphins spread up my leg to my knee. Nothing like nature's painkillers.
