Thank you all for sharing your experience with this. I've never had one of these treatments but, I am headed that way soon. I have an upcoming appointment with a pain management place? I had back surgery 30 years ago. Now, I find out I have Lumbar Spinal Stenosis. Going to have an MRI done so they can pinpoint the exact spot that is giving me issues. My legs are weak. Within 30-45 seconds of standing still in one spot I feel like I am going to fall down. If I am walking or moving around I do better but, after a while walking wears me out. All this and I am unemployed trying to find a job which is very limiting trying to find something I won't have to walk much. It gets discouraging.
