Hello @gardenlover71, Welcome to Mayo Connect. I don't have pain with my neuropathy and I tried a infrared light therapy device early on but it do anything for my numbness so I stopped it. There are a few discussions on the topic where others have share their experience:
-- Anyone try LLLT red light therapy for helping with PN?

If you haven't looked at other complementary or alternative therapies, you might want to look at the list on the Foundation for Peripheral Neuropathy site here - https://www.foundationforpn.org/therapies/.

What type symptoms do you have with your neuropathy?
