In getting the x-rays to make sure nothing else was going on, the right knee was also imaged. Turns out that knee has a bad fitting knee cap, and i can expect some (more) arthritis there. It was bothering me more a year or so ago, but not so much these days.
So, i might get a little chair for various gardening tasks, but in general, no change of life. Yay! But my excuse not to go to the Saturday morning exercises goes away. Sigh.
