What to do when one hip is higher than the other when it looks like one leg may be longer than the other

I have found Myofascial Release to be wonderful for this.
My client's hips were even after the treatment today.
I remember the first client that I ever helped their hips to be even. They needed to wear an insert in one of their shoes to even them out. After the session, they left their insert on the table and wrote on it, "Thank you"! I will never forget it.
Myofascial Release is a gentle, and powerful treatment.
