@dbeshears1 Debbie, I believe your approach to this is absolutely on target. Each one of us with PN know our own body. We know when things aren't right. My primary doctor, not neuro doctor ordered an MRI of the brain in 2015 and a follow up in 2018, all good. Little humor: She called me and said, "there's nothing there". We both laughed. As we know, in medicine, doctors will usually want to rule out the worse things first. After going to six various neurologists since early 2015 in four different states, I've come to the obvious conclusion that there is one heck of a lot of information about PN that doctors just don't know. I agree with you. I've learned more about my PN from others with PN. And, reading your various posts, you did have some unusual circumstances involving your onset of PN and no doubt, both small and large. I'd assume that as well and seek best treatment, if any, going forward on that basis.
