John - Go to a physiotherapist.

For years I walked around with one leg longer and a slightly protruding hip. I thought it was because of my scoliosis. Much to my surprise, my hip was locked. I layed down on a table and the physiotherapist literally pulled my leg (don't try this at home), I heard a pop, and now my legs are the same. It will also prevent you from having back pain and all kinds of other problems.
