~ It's going to rain! ~
Ever since I had the TKR 6 years ago, and then a revision 4 years ago (just before I moved to VA), whenever the weather is about to change – rain, snow, sleet, etc. – my knee hurts. It usually hurts when I get out of a chair, but this is pretty much all the time. So, then I put on my soft knee sleeve which provides just enough pressure to prevent that. I'll have to wear it today, and probably for the next several days. It's getting a bit too "stretchy" as I've used it so much, so I ordered a new one (a different type). I joke that I'm a better weather forecaster than those who get paid for it!
