Heh, heh, it's likely one of those heads I win, tails you lose. IOW you can't have the knee surgery until you at least try the shot first. If you get the shot, you have to wait 3 months. (Just SWAGing that as I've seen too many examples of such non-sense in my long time on this Earth).My wife got a cortisone shot in her knee and it lasted three days so she wanted to proceed with the replacement surgery. That's when she was told that getting a cortisone shot automatically delays any surgery for 90 days. I don't know if that is knee-specific but folks may want to find out if they are considering surgery.
