OUCH!

I messed up my right knee in April.  It still bothers me.  But I know what caused it.

Last night. I did something that messed up my left knee.  It is as if I hit it on a door frame.  But I didn't.  Can't think of anything I did to cause it.  Damn...

I guess I'm going to have to see a doctor...  I used to just heal in a week from these sorts of problems.  But not any more.  Getting old is really annoying.
