Sorry to hear of your suffering. It is terrible that our Country has made it difficult for people truly suffering to obtain relief. People with chronic pain cannot function without opiate pain medication.
I recently tried radiofrequency for low back pain. The nerves causing the pain are burned with a hot needle. They do grow back eventually. Don’t know if you would be a candidate but, I feel 10 years younger. Might be worth asking. Good luck!
Radiofrequency is what NV pain management doctors refer to as ablation. I've had it done with success on my neck and recently, without success, on my back. I haven't given up on the process, though, as it took two times for it to work before.
