I have had a Rebuilder for over 10 years. When things are particularly bad at night, I use it for a soak, although if I had to do it now, I would either get a less expensive unit, or just soak in Epsom salts.
I do feel a bit better after a session, which might also happen with just a soak; I don't believe it's reversing the condition.

I was very successful in reversing neuropathy, and the Rebuilder was part of my program, along with the usual supplements (minus ALA), doing some heavy metal detox per Andy Cutler, going gluten free and eating antioxidant-rich fruit and vegetables. The Rebuilder definitely sped the process.

I had a quick onset PN after medication. Within about three months I was in a wheelchair because I couldn't feel either foot, I felt numbness up both legs and into my lower torso, and had shooting pains in my hands and arms. I was wobbly while trying to walk, my thigh muscles were degenerating. I have a phobia about doctors for conditions where there is no known medical treatment, so went straight to alternative healing modalities, and just dove in and spent the money for the Rebuilder. I figured I had to act quickly.

One thing I did that was really important was wearing warm socks and sock warmers 24/7 for about three-four months. Any time that my feet got cold, I felt an immediate loss of improvement. And this was during the summer!

Within a couple weeks after starting with the Rebuilder I was about 75% better, with greatly reduced numbness in my feet, my hands and arms completely better, no numbness in the thighs and torso, and my legs stronger so I was no longer wobbly. Today I'm about 95% better with some numbness still in my toes and in my feet if I do not remember to do the Rebuilder. I've started using the foot socks instead of the bath as the bath was becoming a bit too much work.

I can't say if the other modalities (epson salt baths, tens machine) recommended in this thread would have worked as well as I did not try them. The Rebuilder, last I looked, was much much cheaper than previously, $800 rather than $2000. Still too expensive, IMO. I have no connection to the Rebuilder Medical company.

I was thinking about buying the Rebuilder. Do you still recommend it?
