Hello i have been diagnosed with 3 herniated discs and spinal stenosis. I have lived with the pain for 6 years. Finally went to neurosurgeon had a spinal shot of steroids that didn't help much. So he started me on gabapentin. I have been on it for 4 weeks now it is doing a great job for the pain but the feelings i have with it is becoming not so good. I am now having diarrhea every day, i'm feeling more dizzy and feeling faint. I found this forum and hope to learn a few things more about this drug and the side affects.
