As a retired 73-year-old male whose 41 year career as a professional healthcare worker, I believe that I am qualified to answer this question.

I was diagnosed with “severe axonal sensorimotor polyneuropathy” during my treatment for stage four AML leukemia in 2012. During that time I have visited over a half a dozen so called neuropathy clinics throughout New England. One of those clinics was in the basement of a six story brick apartment house in New Hampshire. Every one of these clinics stated that they had extremely good results with their treatment of neuropathy.
I spent thousands of dollars seeking some sort of relief. I have included a link to the continuation of my story here. My advice is to stay away from those clinics.

There is no universally recognized "true cure" for neuropathy. The effectiveness of treatments largely depends on addressing the underlying cause of the condition. In some cases, if the cause is identified and treated promptly, such as correcting vitamin deficiencies or managing diabetes, it may be possible to reverse or significantly improve neuropathy symptoms However, for many patients, neuropathy becomes a chronic condition requiring lifelong management of symptoms rather than a complete cure.

Personally, I got tremendous results with the RST Sanexas therapy.

Treatment Approaches
1. Addressing Underlying Causes: Managing conditions like diabetes or correcting vitamin deficiencies can help alleviate neuropathy symptoms
2. Medications: Various medications are used to manage symptoms, including pain relievers, antiseizure drugs (e.g., gabapentin, pregabalin), and certain antidepressants (e.g., duloxetine, nortriptyline) However, these treatments often involve trial and error, and their effectiveness varies among patients2.
3. Lifestyle Changes: Quitting smoking, exercising regularly, maintaining a healthy diet, and avoiding excessive alcohol can help manage symptoms and prevent further nerve damage.
4. Natural and Complementary Therapies: Options like acupuncture, alpha-lipoic acid, and certain amino acids may provide relief for some patients, though more research is needed to confirm their effectiveness.

In summary, while some cases of neuropathy can be improved or reversed by addressing the underlying cause, there is no single "cure" for neuropathy. Treatment typically focuses on managing symptoms and preventing further nerve damage.
