I do...and pretty regularly. This started to happen last year after my RSD spread to my upper body and got significantly worse. I also have an a pretty fast heart rate all the time now (always over 100 and often up around 160 when the pain is particularly bad). I had a lot of tests done and the conclusion is that it is related to the RSD...probably a result of the high pain levels since it gets worse when I go into a bad flare.

I have also had the dizziness, nausea, weakness, and sweating (plus balance issues, a ringing in my ears, nose bleeds, and blurry/double vision) and these were all caused by the RSD. It's definitely good to get it all checked out because you don't want to ignore something and just assume it's the RSD because if it isn't you could be ignoring something that could be treated and allowing it to get worse. But if you can't get any answers from the specialists then it could definitely be caused by RSD.

I'm sorry that you are going through this...I know it is not a fun situation. I went nuts last year being bounced around from one specialist to another with my symptoms before the conclusion was RSD...and only came to that conclusion after I did the research and found out RSD can cause these things and brought the info to my doctor. The sympathetic nervous system can do some crazy stuff when it is malfunctioning...
