I've been nursing a bum right knee for about a year... busted it up swinging a leg over the scoot last summer....   I'd been putting off doing anything hoping that it would heel up by itself.  Yesterday it got so bad I couldn't even walk on it.  Damn it hurt.  So off to the Docs I go this morning.  Torn miniscus.  A shot of cortizone cocktail and I'm mobile again.  I may need an operation to clean things out of there.  The Doc kinda hesitated about recommending the op untill I asked him if my name were Joe Montana would it make a difference...    Gotta go mow the lawn now....
