vulvodynia
"I was prescribed gabapentin a year and a half ago for Vulvodynia.  Initially, gabepentin did not help with the burning.  I had to go way beyond 2000 mgs.  Once the dose was increased, it definitely helped with the burning nerve pain. I would say it cut my pain by about 60%. Unfortunately, I have had to add other medicines to gabapentin overtime to help with the burning pain.  I added Lyrica and then Cymbalta.  I'm on 3600 mgs of gabapentin along with the other two medications.  My burning is pretty bad again.  Gabapentin worked for awhile but, now I need to switch medicines.  I had no side effects on this medicine."
