I got peripheral neuropathy from Flagyl. They don't really know how to treat it yet. I got tested by a neurologist first, and he put me on Lyrica and Cymbalta I think it was. The side effects were too awful, so I discontinued. The problem with drug induced neuropathy is that even after you discontinue the drug, it's still in your system and continues to do damage. I told the doctor as soon as my toes went numb, and he took me off Flagyl. The neuropathy continued until I was numb half way up to my knees, and my hands were affected. That was five years ago, and I still have problems with my fingers, and my feet are numb. It has been getting better, and I don't have to use a cane anymore, but it can take years. See a doctor asap if that's what you think it is.
