Just chiming in after reading some posts.
I get bouts of being chilled all over. My wife freaks out as I sit outside in the sun in 90 deg. weather and shake from being cold. All the while being in burning pain. My RSD started in my left wrist but has spread to the my left side of face, chest, kneck and I'm noticing tingling in my left leg from the knee to my toes. The Lyrica I take usually controls the pain good except when this happens....
