HFX/NEVRO Stimulator for Neuropathy

I have had neuropathy for several years as well as back pain (result of back surgery (lumbar laminectomy) and have in the past gotten cortisone shots for the pain. The last time I went to my pain doctor, he recommended that I see a neurosurgeon to discuss a fairly new device specified for neuropathy and back pain.
I visited the neurosurgeon and he told me about the device. It is a spinal simulator with which they have also seen positive results for back pain and also for neuropathy. I agreed to try the device and a test was scheduled to attach a test device externally. I did the test for a week and the results were positive. About 90% of my back pain was gone and my neuropathy, although still there, was better.
Following the test period (one week), the neurosurgeon and I agreed that the device would work on my pain and I was scheduled for surgery to implant the stimulater in my lower back with leads attached to my back (epidural area).
I have had the implanted device for almost 2 months and have been trying (with help from the HFX coordinating team) to find the right setting on the device. I have experienced dome pain relief in my back but little to no relief in my feet. I am still working with the coordinating team to find the best setting.
Sorry this is long but I would like to know if anyone else has had experience with the device.
Thanks for any input!
