I think I know what Kitt will say..... so I'll let her handle that question.

Here is a list of the tests to determine if someone has PN....
It is by Dr. Latov from New York, who is an expert on them.
So check out your tests and see if any have been missed:

If you get diagnosed too soon with a hereditary PN, without confirmation by DNA testing...you may close doors to healing or reversal or stopping progression that exist.

You still have not shared with us, what other drugs you take, and your test results. It is your choice whether you choose to do so. But please understand that doctors often do not understand neuropathies well. This forum is filled with stories of doctors who dismissed the poster with a premature diagnosis of idiopathic when more could have been done. Some things are up to you, as well... you need to become proactive in your own PN experience. You can choose not to, of course.
