Do not be afraid. If you are in moderate to severe pain, then it is worth going through the procedure! Do you know and trust your doctor? I have had numerous and various type of treatments to treat degenerative disc disease and spinal stenosis. In my case, some treatments work and others don't. Did your doctor give you a valium to take 1-2 hrs. before the procedure? It will help to calm your nerves. The only time none of the treatments worked on me was due to severe degenerative disc disease in my neck. I ended up being treated by a doctor who practices functional medicine. It was expensive and took about a year of regular visits and treatment. Now I am on maintenance and it is working. For my stenosis, I continue to see a spine interventionist doctor. He is terrific and without both types of treatment, my quality of life would be a living "hell!" These are stressful times and removing one stress is significant. It will have you to return to a less physically challenging time! Stay well, safe and be at peace!
