I had pain in the lower back so I went to a physical therapist. I was told that one leg is longer than the other and I need to get it checked out. I went to a chiropractor and he adjusted me and the legs are equal in length. Initially I went to the chiropractor for other problems but he told me that I had other muscular issues and the length thing was not the main thing. That's why after a couple of adjustments, the leg length difference went away.
