postherpetic neuralgia
"I came down with a terrible bout of shingles on my head and left side I'm Dec 2016. The pain was terrible and the only thing that gave me relief was gabapentin and effexor. I'm youngish only 38. I have been taking 600mg of gabapentin and 150mg effexor  antidepressants the combination works for relief from nerve pain. I'm nearly six months with phn. In my experience gabapentin is the best treatment for shingles. The side effect I have the most is constipation buy I take a fibre supplement in my morning coffee. Shingles pain is horrible."
