I did 7 years ago, and at the time it didn’t help me. It had a good feeling, but didn’t help my deeper nerve pain from my PN. The only thing that has helped me is Gabapentin, and I’m fortunate it doesn’t cause me drowsiness or any other side effects. It took a few months to get to the right dose and my pain has been consistently tolerable for 7 years if I don’t miss a dose. It also helped me with intolerable cold (and heat) feelings I’d get in my extremities. But many folks here haven’t had the same success with Gabapentin. There’s a lot of trial and error, I hope you find what works for you very soon.
