The way to address chronic back pain is usually physical therapy, more motion not less, smoking cessation, finding a good orthopedic surgeon to see if anything can be done to stabilize the back, sometimes weight loss
may be appropriate, but maybe not in your case. Epidural steroid and facet injections can sometimes be very helpful to get you moving.
Now, Suboxone as you are telling me is not for your pain, since it does not help it. It is however still an opiate, whether you like it or not.
