postherpetic neuralgia
"I started gabapentin 600 mg 3x daily after I had 2 bulging disk removed from my neck that had crushed my spinal cord. I was a paraplegic but I could feel nerve pain. I couldn't even have sheets touch my legs without pain. It's been a year now I've been on it. I can tell when I'm late taking it. What a life saver. I get blurry vision sometimes and have gained weight (might be because my movement is limited). Might have to take it the rest of my life, but it beats pain pills."
