Whats also weird is one foot is hotter than the other,,my right foot[the worst of the two]gets colder than the other,,maybe from poor circulation that comes from vasomotor interuption from rsd ,but after activity[aqua jogging it turns red and gets hot,,stings and burns like a sunburn,,its not uncommon for one side to be a different temp on me,,CRPSBE is on the money with the stress,,that makes mine not only flare but spread,,,,I pray for a remission for this whole group,,i wish the gov would more activly look for a cure,,,,,,,,,,bobber,,,,,,,,,,,,
