@cecelia19 - As I've posted several times, I was fortunate enough to be accepted at Mayo, Rochester. People from all over the world go there and I too found the place to be a well-oiled machine. They did more tests than any other place and all my tests were done over a 3-day period, several per day. I was unable to select a certain neurologist, they seem to choose the doctor based on prior information I provided relating to my case. I went there for answers. With my PN, they gave me suggestions to slow progression - mainly exercise thru physical therapy....but of course, no cure. As folks live longer, more people will develop PN and as far as hope goes, I think first we will see ways to stabilize PN, reduce pain but a way in which to regenerate damaged nerves, that to me is a huge leap from where we stand today. Best to all and keep moving. Ed
