maybe two years if you are in the process of regenerating nerves. but if the underlying cause isnt found and treated, or in many cases even if it is treated, the nerves will continue to deteriorate. this is why it is important in my opinion to get tested thoroughly and quickly. you have a small window of opportunity to recover substantially in most cases. after that the damage may have progressed past the point of being able to recover. that is not to say you cant reach a state of equilibrium as well where you wont recover completely but may recover partially or not progress further.

For someone who has been to several places, what do you suggest?

My experience was testing, testing, testing...and then "sorry, we do not know." And that was it. No further testing necessary. I was told it might improve, it could get better or it could get worse and there was no indication which direction it would go. It was the oddest experience of my life. Could they really know so little about a disease, how to treat it and its prognosis? The answer is yes and it's called peripheral neuropathy.

Ironically, even spell check on my computer flags the word "neuropathy".
