What she said. And extra hugs, too. Pain is exhausting all by itself, sometimes even when you don't realize how much pain you're in.

One thing to tuck in your memory bank for the far future: Don't put off the knee replacement TOO long. My mom had bilateral TKA last fall. One thing the therapists said over and over again was how well she was doing because she had preserved decent muscle strength. They kept saying that most people wait too long for their joint replacements, to the point where it's simply too painful for them to move at all; and they wind up with a lot of muscle atrophy, a very hard time in rehab, and probably never return to full function.

Obviously you're nowhere close to that yet. But something to remember next time you're seriously considering the surgery.

In the meantime, take good care.
