I looked at your link, glenntaj, and noticed that throughout that list, I saw "asymmetric". I always characterized my PN as symmetric. My question is, do your symptoms have to be perfectly symmetric to be considered so, or do you just have to have both feet/hands affected in some way? I thought that the latter was the case, and that even though my left big toe might be burning, the side of my right foot is what's hurting at that moment. And this can all change in 15 minutes or less.
