does it feel anything like, oh, blowing your knee out? Like when you're out of shape and in your forties and you think you can get on a bike for the first time since you were 12 and immediately ride up and down hills starting at the edge of your driveway? You manage to feel proud that you've gone up and down six times in two days. Next one knee hurts and swells up and you're all like, that's weird, ouch, where's the Ibuprophen. Then a few days later you suddenly can't walk because one knee doesn't work and keeps buckling, and man it sure has this weird swelling thing going on?
Is it anything like that?
