After a simple slip and fall in Dec. 08 resulting in a sprained ankle and a long winter of unexplained pain I was finally diagnosed with RSD in June. At this point it is limited to my left foot. I have undergone 5 Sympathetic Nerve Blocks with short term success. I am now scheduled for RFA in three days. After internet research I am getting some mixed feelings about this procedure. I am most concerned about being able to work afterwards. I am an elementary school teacher and being off work is more trouble than actually being there. Anybody have any post-procedure information?
