If it makes you feel better none of the symptoms you describe are things I encountered with PN.

Mine started with a sensation very similar to a cell phone buzzing inside my ankle. It would buzz for about 1 second every 5 seconds and would continue 24/7. That progressed into pins and needles / burning sensation.

It really sounds like finding a good doctor/neurologist is your best bet. They will help you narrow down possibilities. I'm 18 months into my symptoms and still don't have a positive diagnosis, so be don't stress out about not knowing right away.

Finding a way to calm down and de-stress is critical. While they say stress can't trigger a flare up on it's own, it can exacerbate your existing symptoms and make life miserable for yourself
