my knee update
		It's fine.  As of today, it's back to "normal", where "normal" is "not really right, but it's never going to be right and I'm ok with that."  Tomorrow, I will try it out on the elliptical at the gym (aka "gerbil machine").  I think what happened is that I definitely stretched something in an inappropriate way, things swelled, and the swelling made things slide around.  I took a lot of anti-inflammatory meds, and stretched a lot/moved it a lot, and everything's fine.  No doctor visit necessary.  Yay!
