Not sure if it hurts or not ...

So, at 11 am this morning I was thinking to myself how my knee didn't hurt at all today. Doens't even feel like anything. It feels like ... a knee! (Which is a lot like an ankle, although there is the strangeness of pants rubbing against the numb spots (which I don't feel) and then suddenly against the non-numb spots, which I do feel.)
I even ran 20 steps for a train, and it wasn't marvelous, but I don't know that I felt it ...

But then I sat for an hour, during part of which I crossed my legs (in both directions), and when I stood up again, I definitely FELT it. Then I sat for another 2 hours, and then I kind of limped along for a couple minutes, then the pain just ebbed away and was gone ...

Will keep my nerves on it for the rest of the day, but it is a good point - is it the leg crossing that causes the trouble? I will have to keep feeling that out for a while. Or better yet, not cross my legs. I think that I am ok now - will leave the house and see how it goes.
