Be gentle, now. Yes, I should have asked the doc. Instead, we got into a discussion about knee replacement surgery. That kind of took my mind off of the 'how quick can I ride?' question.

This forum has lots of folks with lots of experience dealing with sports injuries and joint issues. I suspect there are some medical professionals, too. The advice I received here seems reasonable, but I don't consider it to be definitive. I'll see how I feel tomorrow, and I'll probably do a short ride (24 hours after the injections) and see how the knees feel afterward. I may repeat on Sunday if Saturday goes well. Monday, I'll call the doc. I ain't real stupid, you know.

I do appreciate the comments and the Google search. All I can say at this point is cortisone is gooooood stuff.
