My Dr. said I should take Gabapentin because it's cheaper than Lyrica and I'm on a very limited income. He has started me on Gabapentin for my back, left leg and left foot pain. It's really for my leg and foot. I have the worst pain, burning, numbness and tingling in my left leg and foot. He said that I could take Lyrica instead of Gabapentin, but that Gabapentin is much cheaper. I'm concerned about all the bad POSSIBLE side effects and other drug interactions with Gabapentin. It just sounds like a RISKY drug. The Dr's actually statement about the two drugs were, "WELL, LYRICA IS A MUCH CLEANER DRUG"... could someone please tell me what that actually means? Or at least tell me what the difference is between the two drugs Lyrica and Gabapentin? Thank You.
