Gray sea: I too have continuing nerve pain in my buttock and posterior thighs following extensive back surgery 3 months ago. It is frustrating because I had the same pain before surgery. I take 1800 mg of gabepentin a day ( 3 doses) and can’t say it really helps. A major side effect for me is brain fog and difficulty forming words/ sentences. My pharmacist suggested I ask about taking Cymbalta, which helps nerve pain in some people. I plan to discuss that. It’s apparent I’d need to slowly back off of gabepentin. What does help my nerve pain, which is present 24/7 is sitting on ice packs several times a day and right before bed.
