You can sign up for suspension therapy. It's copay but by aunt did it for years to treat her back problems. It's not like this where you're upright, but you're held up on your ~~side~~ (EDIT: any prone-oriented position) by slings that raise and lower your hip, lumbar, shoulders, and legs at different angles to get your spine to lean into the "straight" orientation in the lateral direction.

P.S. never go to Chiropractors. Look for certified physical therapists.
