question: Hello~ I was Dx a year ago with RSD after a fall where I severely sprained my left ankle and lower back. I do experience all the symptoms however it is not isolated to my foot. At times the entire left side of my back swells up as well as my leg. When I go for my checkups the doctor only concentrates on my leg and not the complaint of my back? Could there be something else going on? Thanks, Maylene M.
