I had been taking Neurontin for a little while. A Dr. gave it to me for a headache after being on it for about a week and half...when I started feeling some burning in the bladder area....which turned into what seemed like a bad urinary tract infection...but no bacteria showed up...What all this ended up being....I contracted Interstitial Cystitis....and have had to go through awful agony and most depressing periods...because there is no cure for IC. It's an awful disease of the lining of the bladder...I am very angry over all this...
