peripheral neuropathy
"I've been on this medicine since reading about it online last year. Anyway I now take 2400mg/day and my severe face/ear pain is virtually gone.  Once in a while I can feel some pain but it's minimal and doesn't last the days it used to.  Excruciating pain to the point I can't even stand the touch of a brush on my scalp on that side of my head or a face cloth on that side of my face...it's wicked pain that I'd do almost anything to get rid of.
This medicine works well. I take no other pain medicines other than Advil or Tylenol for other minor pain.
