Is it usual to have numbness in feet etc, when taking Gabapentin? I am waiting for specialist to get back with the answer! My Siatic Nerve is playing up, and it is the worst pain ever. Believe me, I know pain. I have FMS. And everything else that goes with it. I am not a giver upper, but how much can one person take really!! I fell and fractured my leg 2012 Dec. I have had not many no pain days. Physio, u name it... now sciatic nerve.
