At least yoou have come to the right place to ask questions....everyone has different symptoms at different times. My RSD came from a bout with an internal MRSA infection. I was diagnosed after no one could tell me why my leg that had the infection would not stop burning and tingling. I still had the pain from the infection even though it was completely gone..after about 5 different neurologists and a year later they finally diagnosed me...then came the year of MANY experiments of drugs and complete and utter chaos...the "cocktail" is not completely right, but for right now it helps. I am going into my 3rd year and the RSD is spreading...I can always tell when it is beginning to go somewhere else in my body because I have the tingling and burning, so from my experience it may be spreading in your body also....I hope this helps a little
