I have RSD in my rt. hand with only minimal swelling! I tested as "mild to moderate carpal tunnel" 4 yrs. ago. So, I had cortisone injections in my wrist. NO relief! but I had burning, tingling, pulsating pain that just disappeared a year later!! Then last year I was in a car accident. I saw the other vehicle coming (I was stopped- he was going 55+) and I braced myself with my right hand. I was sore all over for a couple of weeks. Then one morning I woke up to the same pain but this time I could NOT touch it or let the air blow on it. Ok... MY POINT...Use your own instincts. If you truley think the first dx. of RSD is correct, by all means... GO WITH IT!! I am assuming you've done some research, as well, on your own. Unfortunately there is little info available to us on RSD. Heck, my doc called it Causalgia. So I kept saying Causalgia and absolutely NOT a soul ever heard of that. But then some one kind individual told me to refer to it as RDS or CRPS. Ok, not many heard of that either but I am finding a few! PLEASE DON"T GIVE UP!!! I can't find a doc. either! In fact the one who dx. my "Causalgia" tried to do a NCS & EMG on ME! The Crazy Man!! I refused the NCS but was gonna give the EMG a troopers try! HAHAHA! After the second impulse I was screaming and crying uncontrollablely! The nurses asked what they could do for me and I cried out "Get my records... This is so cruel"! Ohh, did I ever mention to you I have still not been given any pain meds! Don't come to this area if you expect pain relief! I am willing to help you any way I can and so are others, I am sure.
