i started taking neurontin last march2003 for severe neck pain. i had to start very slowly as the side effects were quite severe in dizzyiness and light head. the drug worked very well but about a month after i noticed very severe pain, numbness and burning in my feet.i have put up with this till i am at my wits end. even had cortisone injected into my feet to try to help. that didn't work. really stirred things up. i am going to go off neurontin slowly ,i take 300mg x 4 times a day. will i have bad side effects when i am going off it. i am on a lot of medication and have 3 heart stents. i am concerned that all my medication are interacting with one another
