Any kind of injuries, from mild injuries to the very worst of injuries, can cause RSD. Medical professionals (doctors and scientists) do not yet really understand why a person with a certain type and severity of injury will get RSD while another person with the same type and severity of injury will not get RSD.
On August 25, 2001, I was a pedestrian struck and injured by a car while crossing the street on a crosswalk. I was thrown 40 feet. My RSD started in my left knee, before spreading to my left leg, and then to my whole body. I know many people who had the same type and severity of injuries I had in my left knee, but these people (good for them

) did not get RSD.
If your RSD got caught early, you may have the chance of getting rid of it, but only if it is treated properly, by a compassionate and knowledgeable doctor. I heard Dr. Schwartzman is one of the best RSD doctors. If I had had the financial means, I would have seen him, because I am especially interested in the inpatient RSD ketamine coma procedure. The word "coma" used to scare me; it does not anymore. I think it is like general anesthesia (I had nine of them), but lasts longer.
Good luck to you, and let us know how you are doing.
