A possible source of
our set of
symptoms. Burning, tearing, pulling...then numbness
in non-symetrical fashion suggests to me Herpes Zoster, stage 3. Stage 1 - chicken pox, Stage 2 - Shingles, Stage 3 - an assymetrical neuropathy w/ it's unique set of symptoms such as what we describe.
If I were a research scientist, I'd likely be running some clinical studies., But, alas. The question is, then, Has everone had chicken pox or shingles who is complaining of the symptoms?
