Hi pacugirl. I am kind of in the same boat. RSD right leg 3 years, no noticeable skin changes .... "JUST" extreme pain. The fire-feeling. My leg has 'cycles' though the day - Sometimes it hurts, sometimes my lower leg is on fire (this is new as of a few weeks ago), sometimes pins & needles, and sometimes it just feels HEAVY. I have been reading this forum forever and decided to post today. I go to school in North NY so maybe we're close to each other?
