.....very localized "buzzing" or "vibrating" feeling....
This is a very common symptom of PN.
Are you seeing a neurologist who specializes in neuropathy?
Have you been tested?
See www.lizajane.org for lists on testing and follow-up.
Read thru the 'stickies' at the top of the topics page. You can search them for 'buzzing' and come up with past info.
