Knees/ IT band again!

[OakLeaf]

Well ... my totally uneducated feeling is that if standing hurts and yoga helps, it's some combination of feet and low back. Knees are basically at the mercy of what goes on above and below them. I forget what exercise program you're doing, but I guess if I were you I'd really be emphasizing flexibility and strength in the feet, hips and lumbar spine. (Which I am, actually, though my knees are the least of my troubles right now ). When you're standing, concentrate as much as you can on standing on four corners of your feet. Do your little foot exercises inside your shoes, and standing pelvic tilts and clocks, when you have a moment at work.

Good luck... (and as I said to someone else and I might've come off condescending, though that really was not my intention - there are plenty of free anatomy charts online, and it can be REALLY helpful for me to look at them when I'm trying to nail down what's going on)
