Welcome to Neuro Talk. I am sorry you are having back issues. If anyone is around your area, they will post. I do have a suggestion. I know Illinois is a bit of a drive, but not that far. Seek a teaching hospital. I am very much in favor of seeking treatment and DX in teaching hospitals. Loyola University center is where my father went. He got the very best of care and DX.
This is in Illinois. Seek multipal opinions. I had no health insurance, and I did ask the doctors who did not accept no insurance people, if they would please see me. The local community center where you live may have ideas of where to go to seek help. I know this is not easy on a fixed income, but it can be done. It takes a great deal of effort, and asking those doctors, if they would please accept you. There are organizations within local hospitals advocasy programs that may give you some direction too. I sure hope you can find the help you need. I will keep you in my thoughts and prayers. ginnie
