Thanks! Do you also get all over pain? Like nerve pain and sore mucels? I actually have this thing that happens to me almost every night and its like clock work! My hands and feet turn red and a a bit puffy, they feel supper sensitive and burn and almost feel itchy,and just hurt really bad. I looked it up because I was getting frustrated, and I came accross erythromelalgia, and it sounds exactly like what I have, maybe you ciyld look it up but thats basically what it is! But I havent told my doctor yet, wheneverI always forget what im there for! Aha tnak you for your idea!
