Gabapentin....argh, yes it helped with the discomfort, but at a cost to my cognition. I finally decided that the pain relief wasn't worth the mental confusion. I'm just coming off of a test of Lyrica...it too helped with the pain, but....it caused me to gain 5 lbs within about a three week period. What was so weird about the weight gain was that my activity level and eating volume and content was unchanged, yet somehow my body put on the weight. Another case of me deciding that the relief wasn't worth the cost.
