You should consider looking into Prolotherapy. I had increasing levels of lower back pain since I was twelve. It had gotten so bad I couldn't roll over in bed without sharp pain.

My neighbor was a naturopath, I helped him photograph some before/after xrays of a 70 year old woman's knee (before was bone on bone; she regrew her meniscus and bone spurs disappeared)

I did three prolotherapy sessions (they're painful) with him over a few months and I have been pain free for over fifteen years now. I actually started playing rugby after my first session.
