Glenn, thanks so much for replying. It's really the hands that are the issue, everything spreads up from them. The sensation of numbness began in the index finger on the right and went from there. About 8-9 years ago I had something called Parsonage-Turner Syndrome, which involves the brachial nerve plex. But it was only on the right, and it went away after some months of exercises.

I did have an MRI of the cervical spine. It was negative. And as far as confusing the symptoms with Raynaud's, that's a smart suggestion. But this is well beyond the Raynaud's, especially as I have continual symptoms that are unrelated to temperature. Raynaud's as far as I'm able to understand is more a question of attacks in response to cold. At any event, the recent nerve conduction studies show unequivocally - well, that's what the neurologist says, and I have to assume he knows this stuff - that I have the polyneuropathy.

Again, many thanks indeed for your input!
