peripheral neuropathy
"I have been on Neurontin for over ten years.  I suffered nerve damage following a knee replacement.   I have pain in the knee and pain that radiates down the leg into my foot.  I take 600mg 5 times a day.  I have bad days and not so bad days but the pain is NEVER gone.  I could not live without this medicine as it at least curbs the  pain.   The only side effect I can speak of is sleepiness.  But it is not bad and on a busy day I can rise above it."
