Redhairedgirl, it sounds like you are further along than me in that you are way more sensitive than I am. Im so sorry.
I do not work outside of my home this time of year, I am only forced to work outside during the spring to july months, and this is all new to me, so I am not sure what is in store for me, if it will get worse or not. Right now I can still wear shoes but I almost ALWAYS wear shoes that are slip on and I can remove them quickly.
How long have you had it and what is the cause of your pn? Mine is from hypothyroid. Welcome to the board! I find much help and comfort reading here.
