Hey pbrown-
Yes, I've had 3 EMG's which confirm that I have a "sensory greater than motor demyelinating neuropathy".
Which is just the long mumbo jumbo for PN.. or the type I have.

I also have a secondary axonal loss.. which means not only is the myelin sheeth destroyed, but the axon is as well.

I hope you get some answers to your questions, I read the thread you had posted, but I'm still somewhat new to this myself.

There are some great people on the site who have a TON of knowledge though, who can steer you in the right direction.

Good luck.
