I'm sure you've already tried this, but here go my two cents about back pain. My job is also sitting for 12 hours a day (although much better regulated and not as damaging as yours). Try stretching your psoas, look for gymnastics, cycling or dance stretching. It's been the only thing that has helped me. I started having problems to straighten each morning, constant pain in the lumbar zone, bulging disc. A job partner told me about the psoas stretching and it works! It's the only thing that can make the pain go away. I'm telling everybody I know now! And usually helps a lot. I only need to stretch it once a week but I must be constant if I fail to do it, the pain slowly returns.
