I will let you know. I'm sorry you didn't get relief with the Nevro HFx as I was considering that if this procedure doesn't work. My pain surgeon won't do a stimulater because of my hardware from my double spinal fusion. I will have to find a specialist who can try it. My pain is as bad as it was before I broke my back just in my lumbar area now. I'm at a total loss as to what to do. I''m even considering going to Mayo. The pain is so bad it's making me nauseous.
