Do you mean TENS? Yes, I’ve tried it, along with alpha-lipoic-acid (ALA), Vitamin B-12, Lions Mane Mushrooms, physical therapy. Nothing worked. But not saying any of those might “work” for someone else. Plus the placebo effect can be real

My TENS machine works very well for my lower back pain but does nothing for my neuropathy. It actually made my neuropathy worse the last time I used it.
