neuropathic pain
"I was prescribed Neurontin to block the pain in my lower back due to bulging and deteriorated discs.  The Neurontin effectively reduced the pain in my back; however, the mental side effects were not worth the pain reduction.  I have been previously diagnosed with anxiety and depression, but those illnesses were under control with an anti-depressant.  However, once I started using Neurontin, my depression and anxiety came back with a vengeance.  I had an anxiety attack and could not control my mood.  I was tapered off of the drug immediately and I was back to my old self.  Please talk to your doctor prior to taking this medicine if you have ever had depression, anxiety, or suicidal thoughts."
