My appt with the Mayo Clinic in Jacksonville is coming up @ the end of Dec, FINALLY!!!

I was wondering if anyone has questions for me regarding my RSD (4 yrs now). I was in remission then came out after a car wreck. The last injection I had didn't work at all & now my RSD has spread up my left leg and is starting in my right foot.
Any "Pre-info" questions regarding treatment would be greatly appreciated.
Peace to all!
