Just a thought for you. I hurt my back years ago and had alot of pain going down my sciatic nerve due to a messed up disk. The doctors talked about back surgery and I didn't even want to think of that option. So, I did go to another doctor for a second opinion and he suggested a shot in the back with steriods to try to aleviate the swelling in the disk and the pain going down the leg. It was done as an outpatient, they did sedate me so I would be perfectly still while the injection of steriod was put into the spinal column near the disk.
When I walked into the hospital, the pain had gotten so bad and the resulting leaning walk resulting from trying to avoid the pain was really bad, I literally leaned to the left, could not straighten up my back and was in unbearable pain due to the sciatic nerve running down my leg.
When I woke up from the sedation, I got up, walked straight and had no pain at all. I had to do no lifting for a few weeks and a few other things like heat on the back and bending over exercises, but have not had any issues with my back since then. Occasionally when I overdo stuff I can feel an ache in my back and leg, but if I stop what I am doing and give it some rest, it is fine.
You might want to check into spinal injections, much easier than back surgery and it might work for you.
