--there are a fairly large number of threads that discuss facial symptoms of neuropathy, but they're not always clearly labelled as such from the beginning of the thread; it's a subject that tends to come up in varied circumstances, usually along with some commentary on how some physician claimed that facial symptoms couldn't possibly be a neuropathy symptom.
I am one who had significant facial involvement in his neuropathy, and there are others. Often, if you do a search for "face neuropathy" or "body-wide neuropathy" you'll find these discussions (or just wander back through my posts--warning: there are a significant number of those).
