I don’t know what internal inflation is?? But like the previous commenter stated, PN is all about the sensory experiences. I get all sorts of weird sensations that come and go - some sporadically, like a feeling there’s a spider or bugs crawling on my leg to tingling, shooting zaps, vibrating, numbness, etc. My sensations seem to be more pronounced when I’m more tired or stressed.

I’ve had PN for decades- diagnosed as severe idiopathic (non-diabetic) sensory motor Axonal Polyneuropathy, by nerve conduction studies and many other tests. My new neurologist confirmed that the nerve damage originated by the severe Epstein Barr virus infection I got many years ago.
