what does this term mean? I was reading old posts about axon neuropathy or demyelinating I have never found out what this exactly means.

Does anyone have any suggestions on if there is a way to stop neuropathy in the back of my head/neck? I think tissues were damaged when my neck was stretched. Each night the vibrations start with their buzz buzz pattern and shaky feeling. I don't know how it got to this state so fast. I keep hoping this will go away.
