Hi Belinda and welcome to the forum,
Unfortunately some people can't understand how can you be possibly be in pain if your skin looks so nice and pink and healthy.
As you would know PN is a very deceiving condition to the eye, even to the medical profession who have been taught about PN in their schooling, i don't think i would be alone here if i said i have had even doctors give me that look or impression, like they think its all in my head, its unreal, my own GP wrote once that " this man has a very rare nerve disease " RARE there are millions of people with it, world wide.

Even though its hard not to get upset, its best not to worry if people don't understand because there are a lot of people that just couldn't possibly understand it unless they got it themselves, emotional upset can trigger worsening of symptoms, so its just not worth worrying about at all.

You will find great bunch of people here that are very knowledgeable and very caring and they truly do understand.

all the best
Brian
