Interesting you raised this question. I was fortunate enough to go to Mayo in MN in 2020. I have axonal sensory motor PN, no pain, all numbness and poor balance. The neuro doc at Mayo asked me if I had been prescribed any medication for the PN. I told her that my primary had tried Gabapentin in 2018 (bad reaction, anger issues) and the then Lyrica ((groggy). The Mayo doc said do not take those, with your PN it could make it worse. She did not elaborate any further, perhaps because of the axonal diagnosis? Not sure. I will say it did not help at all for numbness, I was on each med for about 10 days, had to taper off on both when stopping. Again, each of us are different with different causes for our PN. I do see that Gabapentin does help others with control of pain. Perhaps your prescriber can give you best advice. Good luck!
