Gabapentin
"I have a bulging disc (C4) which traps a nerve leading to severe pain in my right shoulder (at worst) and a near constant tingling and semi-numbness in my left lower arm and hand (at best). I've taken Gabapentin before and had been reluctant to try them again because of the drowsiness, fatigue and general weirdness I felt the last time, but the pain got the better of me and so I capitulated. I take 1200mg 3 times a day and so far the sharp shoulder pain has gone, however the tingling has not. Apart from having great difficulty coming to full wakefulness on a morning, I feel completely hyperactive and a little manic- not a bad thing as I'm getting a lot done!"
