My doctor started me on Neurontin for pain that I've had in my back. I was very happy with the outcome. It took the pain away and it is not a narcotic! The downside began after a week or so, I noticed that my feet and legs were very swollen. I read on the package that this is a rare side effect. I've talked to my doctor about this and she discontinued the neurontin. Does anyone know how long it will take for the swelling to go away? I gained about 15 pounds of water weight and so far I've only lost five and it has been about 10 days since I stopped taking the medication. Is this normal?
