My internist, and maybe even my neurologist, told me that nerve growth is so slow it will not happen in one's lifetime. However, I read on the Internet, that there are 100 causes of neuropathy and that if the underlying cause is remedied, then in 50% of cases the neuropathy goes away. So who knows. I do know that the intensity of my pain varies with it having reached a 10 on a few occasions while on some days/nights it's below 3. My neurologist said this is 'normal' for neuropathies. I say BS. It just means that they do not have an understanding of the mediating variables.
