Hi Brenda. I don't have diabetes, but my (so far idiopathic) PN progressed fairly rapidly over about six months. Not as rapid as yours, but still alarmingly fast. It seems to have leveled off somewhat in the last year or so but sounds like the first signs I had were very much like yours, e.g., sheets bothering my toes. I hope yours at least levels off too.
The talk of toxins has made me wonder again about something I've never voiced before: could exposure to toxins say, 30 years ago, have had a dormant effect that only surfaced in the last few years? I'm thinking that's pretty unlikely, but the list of stuff I was exposed to would make you say

! Heavy-duty solvents, arsenic, asbestos, just to name a few. I was a walking toxic dump in my 20's. I'm often amazed that I made to 40.
Anyway, welcome to our family, Brenda. Didn't mean to sidetrack your thread.
