MLS laser, rebuilder (this is a joke but part of the package), "matrix" machine which is basically the older version of what they now call Sanexas. I paid a few thousand for a package because I was desperate like almost everyone with SFN AND because there are plenty of journal articles showing efficacy of laser therapy. Unfortunately it was really hard to know if it was helping because I improved for a few months, then felt horrible, then was relatively ok. After 3-4 months of treatment, I can't say I felt significantly better.

What would my disease progression have been without treatment? Who knows! That's why I was hoping for substantial progress.

Lately (without having gone for laser for months) I've been feeling better, but I've thrown the proverbial kitchen sink at my problem though. I made a separate thread with all the stuff I've tried and my results. Obviously YMMV, especially since no one knows what the cause of my SFN is. Good luck!
