My back problems are almost as extensive as yours. I think you are on the right track; I tried many things in search of resolution. I think of it as a process, sometimes things work for a while then stop and I tried something else. I have had extensive ablation, surgery, PT, acupuncture, massage and surgery. Since 2001, my symptoms and limitations have increased. In 2012, I became inoperable, and my Doc offered me the choice of spine stimulation, or a morphine pump. I chose morphine because my research showed three people, I knew who had received them were not happy with them. Next year will be my third morphine pump implanted, and I have great regard for the engineer who created them. You have to be active in your own recovery, I just read an article about Verti Flex by Boston Scientific this advance could keep you walking. Have a positive attitude, I know how hard it is, but at the end of the day it is your pain and all the efforts you make may lead you to some help with the pain. Good Luck on your journey.
