Kelly, several years ago I had back surgery for a bone spur that was pressing on my sciatic nerve and causing crazy pain. They did a laminectomy, (removal of the lamina, half of the little roof shaped thingy on the L4 vertabra) and a forenectomy to relieve pressure on the nerve.
I also had a bulging disc but my surgeon felt that to intervene surgically there could make things worse. Prior to the surgery I could'nt stand for more than a few minutes at a time without pain. Post surgery I had trouble sitting. I was off work for almost a year and a half and did a lot of physio. The first place I was sent was useless so I called worker's compensation and said that their money was being wasted so they sent me to a different clinic where they worked with me on exercises to strengthen my core abdominal muscles. They involved Kegal like exercises and small movements, not hard to do at all, and I also did a lot of pool exercises with foam dumbbells for resistance.
My surgery was extremely successful but I also had a lot of work to do myself to get rehabilitated. I also purchased my own TENS unit and wore it constantly as a distraction from pain. Didn't cure anything, just distracted me. Your situation sounds different especially the partial collapse piece and I have no advice really. I will say that this was the hardest time I can remember in my life and the pain was not excruciating but it was ever-present and it ground me down as if I were slowly being grated. I think I might have been clinically depressed also but once I got hold of the exercises I at least felt I could do something.
I think I'd get a couple of medical opinions about what options exist and the pros and cons of each.
