There are a lot of the chiropractor clinics that claim to "cure" neuropathy but I'm not aware of anyone who has received stem cell therapy that fixed their neuropathy symptoms. Back in August of 2018 we had a guest speaker who has done a lot of research on stem cell therapy at the Minnesota Neuropathy Association. I took notes and a lot of links on his talk and while some of the information was hopeful, I don't believe there have been any breakthroughs yet.

Speaker: William Hoffman of the U of M Medical School
Topic: Stem Cells and Regenerative Medicine: A Revolution Picks Up the Pace

I guess I would do a little research of the science involved that the chiropractor is using. You might find this handbook helpful also.
