Knot: Thank You so much for this information. Due to your post I now have a better understanding of what is going on with the SI joint and that this issue may not magically go away. My second PT gave me a basic understanding of what the SI joint does but didn't go through the detail that you did.

Last year I suffered with pain in my right hip, knee and foot. Several different Drs., 4 mos of PT and an MRI didn't shed light on the problem. The 1st Pt said my right side was weaker than the left but he couldn't figure out why. When I'm in rehab for an injury I faithfully do my exercises prescibed by my PT but the prescribed exercises to strengthen my right hip made me hurt more so I quit doing them. I resorted to bracing my knee when I exercised because it made my hip feel better. The MRI showed osteoarthritis in my right hip and SI joint, which was attributed to the source of my pain, except my PT said I didn't move like an arthritic person. When I was released from PT I was still experiencing pain and had no resolution as to the cause.

I saw a PT who did bike fits because I couldn't ride. Instead of a bike fit he decided to check me out and found my left SI joint was locked. One exercise prescribed and 3 visits and all the issues went away, including the knee pain which had been diagnosed many years ago as chondromalicia.

I copied your post to my exercise blog so when I do things that make my SI joint angry I have reminder of what is going on. Please continue to share your wealth of knowledge with us. It is very much appreciated.
