I have had neuropathy for around 4 years due to chemo. I recently found a place in Memphis called Wellness One. They offer a treatment using vitamin injections and electrical stimulation to reactivate large and small fiber nerves.
I have been going for 2 treatments a week around 3 weeks. (average treatments last 5-8 weeks) FDA approved. So far I am optimistic and things seem to be working. Check it out there may be a location near you. Good luck!
