My mom mentioned that she had feelings of burning feet throughout her life although has never been diagnosed with PN. She seemed puzzled when I mentioned some of my other symptoms and how bad it had become.

Could be something to it. My pain and symptoms sounded way worse than what she described. It was more of a annoyance rather than a pain in her eyes. I tried explaining that at times I struggle to stand/walk through the pain. Maybe it's hereditary and I got it worse? I wouldn't rule it out, it just seems like there is more to it in my case so I'm not just going to lean back on hereditary PN as the diagnosis right now until I do more investigating.
