I have the frozen feet,sometimes sheets and most texturs I can't tolerate other then what I am used too. For awhile socks cause pain though like I said I have frozen feet when even a little cold. I was getting migranes and do still get head aches. The insomnia is unreal and I am on many sleep meds.My condition though is also RSD which is very common to have these issues. Have you looked over on that board too. I am not sure where your condition is but I have PN and RSD. Sorry if I am way off base. Feel better
