Hello and Welcome
I've got P all over my back, patches on my chest and stomach, knees, bum, genitals, feet, head, eyes and ears...god I sound like a walking flake factory lol.... I've only had it about 4-5 years. It's not affected my joints although through years of Football, Rugby and Karate my joints are shot anyway and I wouldn't know it it was lol
I find the thing that I hate the most about P is the constant checking - seats after you get up, shoulders before you go into a meeting or meet someone, visible skin for flakes most likely to attract attention... I send more time looking in mirrors, shop windows and reflective surfaces than any woman I know (no offence ladies ;-))
Hope this site helps, I find it's great to just read about other peoples experiences, thoughts and feelings on here...good luck
:-)
