I am still working on it.  what I have been doing is stretching my hips and quads.  I also believe the pain comes from the sacroiliac joint.  I only have the pain when I transition from sitting to standing or vice versa.  I have been getting massages a few times a month and using my Teeter Hang-ups.  The pain seems to be going away slowly but my goal this year is to have it gone completely.  It doesnt prevent me from running or lifting weights.  I have seen a spine specialist also and he has cleared me to do all physical activity.  I am going to document my list of exercises, and stretches.  Check out Gary Crowley on youtube also he has some good advice for lower back and hip pain.  Good luck.
