@stantallusa, I added your question to the Spine Health group (https://connect.mayoclinic.org/group/spine-health/) as well as the Prostate Cancer group. In the spine health group you will find several discussions about spinal stimulators. For example:
- Comparison of Spinal Cord Stimulators from Boston Sci., Nevro https://connect.mayoclinic.org/discussion/comparison-of-spinal-cord-stimulators-from-boston-sci-nevro/
- Has anyone tried the HF10 Spinal Cord Stimulation Device? https://connect.mayoclinic.org/discussion/hf-10-spinal-cord-stimulation-device-relieves-back-and-leg-pain/
- Has anyone had the Stimwave spine stimulator installed? https://connect.mayoclinic.org/discussion/has-anyone-any-had-the-stim-wave-installed/

Stan, it sounds like the source or cause of the pain remains unknown. Is surgery an option?
