The worst of my hip pain was when I was sitting or sleeping. Interestingly, riding my bike didn't really hurt.

I don't begin to understand it all. I just know that our bodies compensate for weakness, injury and the like in some really intersting ways, some of which lead to pain. That's what made me think that your saddle being too low (if I remember your last mention of the subject, it was still an inch too low--which is a lot) might be a contributing factor as you're limiting your leg and hip's natural range of motion. Something within you might be overcompensating for that.

With that, I totally and otherwise defer to whatever Knotted may have to say!
