long time away

First I spent 11 days in San Diego, and didn't want to advertise I was going. Just a few days before I left, I was at the gym working with my personal trainer, and twisted somehow as I sat down, and got a really bad "owie" in my left knee. Had to switch from using my cane to using the walker. Had it X-rayed and nothing was broken. Missed a lot of water aerobics, because I could not walk that far, even with the walker. Then, after I got back, among other things I had a crown removed that was decayed underneath. Haven't felt well - just keep adding "owies"
