Hi @lois6524, I have the same concern. Unfortunately I learned a little late and have spent a lot of money on things before I researched them only to find out they didn't help my symptoms no matter how great they sounded. After I joined Connect I found recommendations from others and a few sites that help you research the validity of some of the products preying on folks with neuropathy, including a discussion here on Connect.

Google Scholar is also a good tool for doing your own research on the latest medical research -- https://scholar.google.com/

I don’t think we can make a blanket statement "that neuropathy can't be cured",it depends on the cause of which there seems to be hunderds For example, peripheral neuropathy caused by a vitamin deficiency can be treated -- even reversed -- with vitamin therapy and an improved diet..
