I have been told since my early 20's that I had one leg shorter than the other.  Regular chiropractors told me this and even gave me a heel lift to wear in my shoe.  In my 70's, I kept getting what I called hip pain, and regular chiropractic treatments did not alleviate this.  I decided to try the upper cervical direction.  After seven treatments my pain is gone. It was identified as sacroiliac pain.  Since my seventh adjustment, my back has stayed in alignment for seven weeks.
