It's true that for many years the medical/science community did not think nerves could regenerate, but new imaging tools and (finally) more research there are findings that have increased the body of knowledge for metabolic treatment to stop progression or repair damage to nerves. There are so many reasons for NP that treatment really depends on whether the cause is structural or metabolic. Chiropractors seem to have gotten involved when the root cause was structural because so many of their patients with physical damage have neuropathy. But the other causes are metabolic --diabetes or prediabetes being a major one but B12 deficiency, heavy metal contamination and a host of other reasons. They require some other approaches. It is true that nerve repair is slow but is possible in some cases. I think a key though is to stop the progression. If the cause is metabolic, it seems that a lot can be improved with lifestyle and diet changes.
If you want to learn about some of these relatively newer findings I suggest going to research sites like the National Inistitute of Health, John Hopkins University, the Mayo Clinic. I found a lot of research through NIH--if reading scientific studies is something you are comfortable with--you can see a lot of this info even goinig back to studies from the 1990s. Some of these major research groups and treatment clinics have synthesized information which is easier do read and consolidates studies or provides lists and links.
Like you, I'm also very wary of some 'treatments'--especially grandiose ones that make it seem easy (like a one pill 'cure-all'). That's why I'm taking time to do research on various sites. NP is complex and, from what I've read about treatments for metabolic NP like mine, I will need to up my lifestyle changes but there also are well-documented tools that might aid in stopping the progression and (I'm hopeful) potentially help heal some of the damage. Luckily, so far my damage isn't extreme but now is the time to work on it and I'm willing to look around and examine optiions.
I'll continue to post if I do try the Blueprint approach--or some part of it--and gain solid success . I'm also not afraid to say I tried something that didn't work and it's important to share that. So far? Gabapentin is only a mild treatment that goes system-wide so can create unwanted side effects. ALA supplements recommended by my neurologist actually has helped with reducing my symptoms and makes sense in my case. I also didn't realize till I just did the research that being 'pre-diabetic' as I am can mean it's a significant contributing cause to my NP. Thought I was safe because I wasn't officially diabetic. So lifestyle changes are next perhaps along with some of the other metabolic treatments that may, indeed, utilize the body's natural angiogenesis process to trigger blood vessel growth and feed my ailing neurons before they die. Who knows? Won't find out if I don't try.
I hope you don't give up because you think it's hopeless. It may not be. Resources for working with NP will come from different health arenas because there are so many reasons and conditions of NP. One doc can't do it all.
What if they've done every test that's available, only to have them all show nothing out of the ordinary, and you're given a diagnosis of idiopathic poly neuropathy?
In other words, the cause of my neuropathy can't be determined. It's only progressed and intensified over the past 10 years. I can't envision any kind of wonder treatment that's ever going to help me in any way.
