Nevro HFX is spinal cord stimulator. It uses higher frequency energy that other SCSs. I had my old Medtronic SCS battery replaced with the NEVRO about three years ago because the Medtronic unit had stopped giving me relief. The NEVRO did not help, but it was more likely the paddle. Testing revealed that some of the electrodes had burned out. Who knows?

I would say that you might try the trial. It is minimally invasive and should give you an idea of how well it will work for you. Just be forewarned. A number of people have had a successful trial but not with the permanent implant. I wish you well.
