@janetdh, @mikween, and @swiss have mentioned the Scrambler (MC-5A Calmare Therapy) and may have more information.

This is the article that I saw. But I know nothing more about it!

Here's another article that reviews the device and patient's that have used it.

Scrambler therapy: what's new after 15 years? The results from 219 patients treated for chronic pain (Jan 11, 2019)
-- https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6336541/

I have personally tried Scrambler Therapy for my idiopathic neuropathy. I was in pain for 10 years. I spent thousands and have tried many different therapies, but nothing worked longer than a day. The only exception was the Scrambler Therapy.

By the second session, the pins and needles were completely gone. I had a total of 11 sessions and the pain has not returned! My quality of life has returned. I'm more active and happier not being in pain any longer.

I highly recommend this. You will not waste your money nor regret it. Currently, there isn't a cure for Neuropathy. Remember this is not a cure, but it will actually stop your pain!

I had a prelinary evaluation and 1/2 hr treatment in Chandler AZ. I think I saw improvement, but could not follow through because I was headed out of AZ for Summer. Could not find a provider in MT. Unrelated back pain forced me to a chiropractor here in MT for Back pain and his speciality of treating Neuropathy with a: Rebuilder (beefed up tens unit), Red light Therapy, and a host of supplements and office visits. After 4 days uncertain as to results. I posted a longer message on another message board on this Mayo Site.
