answer:I was hoping someone would have an answer, as my father has nuerophathy caused by having a vein removed from his leg to do a heart bypass. He’s gone to the pain clinic and tried just about everything, everything that would keep him conscious at least, and nothing has worked for him. So I just looked up your medication, Metformin, and I’m surprised that it has helped you, because so far everything I’ve read about that drug suggests that it can cause permanent nerve damage. Yikes!
