Evidently I effed up my knee pretty good at the gym today. It had been bothering me in a minor way for the past few weeks, not enough to keep me from working out, just annoying. Today I was midway through a 5k run, cruising along at 7.5mph when all of a sudden wham, sharp pain. I hit stop and tried to shake it out, no joy, lifted for the remainder of the time I had. Now having sat at my desk for two hours I've got a pretty pronounced limp when I try to walk. Not good.
