I did ask my neurologist what the primary feature was in my neuropathy and he said it is probably most likely an axonal problem that is now affecting the myelin. For him to use the words PROBABLY MOST LIKELY, to me that means he is not a 100% sure if the axons are being affected first or if it's the myelin that's being affected and causing problems with the axons. I guess my NCS results were to mixed to be able to make a 100% distinction in what's actually happening with my nerves.
