My pain doctor has tried a couple of non invasive treatments. Failures. His next suggestion is medical grade TENS, which I may try. He said Medicare covers it, which is unusual for pain clinics. I went to a podiatrist for the first time yesterday, to address the purple/red & odd skin texture of my feet. No answer. I've had vein ablation (disaster, made my neuropathy worse). The cardio vascular "specialist had no answer. My PCP has been aware of this for 1.5 years. No answer. Evidently, I am the only neuropathy patient to ever have this condition. Absolute, medical mystery. The podiatrist suggested seeing a vascular doctor! HA! Back on the merry go round.! He also referred me to a DIFFERENT pain doctor to consult on Nevro HGX spinal stimulation. I've had MRI's, Ultrasound, Nerve conduction, 2100mg of Gabapentin, blah, blah, blah. Sent him all my test results. Appointment on June 12. Do I have the courage to try another experiment? I dunno.
