I have RSD in my left foot. The excruciating burning pain is eating away at me. I have lost the use of my foot. Mine came about after I was in an auto accident. I needed spinal fusion and immediately following my surgery my foot swelled and the pain never subsides. It has affected my enter life, left me permanently. I am at the mercy of narcotic meds...but the drs don't like to keep raising the dosage, meanwhile I suffer.
