whats the plan of action for a horribly bruised knee?    no swelling, worst is on top of kneecap. ran last nite, went ok til i went into a too-fast pace, was sore during but didnt slow me down. but after, oh man did it hurt! still hurts. got a 50k on sunday, do i just rice the knee til then, no runs?

do you know if wrapping a bruised joint is helpful or would make things worse?

By "bruised" I think black and blue from a direct blunt trauma -- did you fall or slam into something?
If the swelling seems to be in the joint itself I would NOT be running on it.
