Hello Esther,
About a year ago I began having pain (an acute pinching) in my left hip area when I brought my left knee into my torso and also when I rotated my left leg inward (such as in a lying hamstring stretch, figure c on page 209 of your book). X-rays were normal, physical therapy did not help, and I eventually began seeing a chiropractor, who told me that my pelvis was out of alignment. After some adjustments, the pain in my left hip got somewhat better, but I started having a similar pain in my right hip, which also presents when I sit in a simple cross-legged position. This initially made sense to me, given that my muscles may have been working differently after the adjustments, but the pinching feeling doesn't seem to be resolving. I am working my way through your book and wonder whether you have any advice for me. Many thanks.
