Interesting thread here. I haven't gone through pregnancy (likely because I'm a guy ), but I do have a situation where my right hip is about 9mm lower than my left hip. This has, I think, resulted in a functionally shorter right leg and apparently (according to PTs and chiropractors) is a cause of my butt/back/hip/foot/neck pain. ng88 - when you said that your pain has improved, is that in situations where one of your hips is still lower than the other, but you just don't have pain because you've done the SEP? Or you actually feel the hips to be aligned because of working on the SEP when you're not in pain?
