I have CRPS type II from a venipuncture injury to the radial nerve in my right arm. It spread up the arm to the entire right upper quadrant of my body, then later down my right leg. Thus, I now have symptoms in only the right half of my body, including the right half of my face/neck/head. I've never noticed symptoms in my throat, but have had symptoms in my mouth, particularly the right half of my tongue & lip (which is a pretty freaky feeling) during flare-ups.
