Hi, T $porter1
How was your PN diagnosed? Did you have the EMG tests from a neurologist.
You can have RX for one of the drugs that helps with pain/discomfort.
I can say, in my experience (and I'm NOT a medical professional) it is very unlikely that PN can be treated or reversed in most cases.
Your neurologist can test for a variety of possible causes and suggest a variety of treatments, based on the tests.

I can't find much about how Polycythemia is treated, but I'm sure you know.
Check with your physicians to gain a clear picture of what can be done.
Depression is a hallmark of PN. So sorry.
