First off I am not sure exactly where your pain is located or what diagnosis you have been given. You did mention that a pain pump has been considered, and that is an option. I lived with back pain for several years and after my first surgery I was worse off than before. That led me to become very depressed and unable to function in simple daily activities due to the intense pain. I went through several Nerve Root Injections, with no success. I was told another surgery was not an option due to the build up of scar tissue. After about 2 years of this they finally decided to implant a neurostimulator in my lower back. I has made a world of differene in the pain I was havin in my legs. I can not get up and function in most everyday functions. I still have some pain in my lower pain in my back but I go in every few months for Nerve Root Injectios to address specific pain areas. In closing I would note that everyone is different , but for me this has helped me to be able to engage in life again, I will always have some degree of pain but now I can manage it alot easier. Search the web and become informed on options available and then go in to your doctor and see what might work for you. Good luck!
