That's exactly what Dr. Bautrant thought was the problem in my case. I had chronically strained ligaments and pelvic misalignment causing pain primarily on one side. I don't know if I would have gotten better by just waiting but after 8 months of doing almost nothing and living on the couch I was not getting better so I opted for surgery. It turned out to be the right thing for me.
I have sacral pain at times -- I'm pretty sure it's from the ligaments.
