I hate the sweating. I NEVER used to sweat and was always cold. My mom used to joke because even when I played sports I would only "mist." But ever since the RSD pain spread to my upper body I sweat all the time. But the cold makes the pain worse so it's like I can't win. I didn't have the sweating though when it was just in my foot. That's not to say that you can't though because RSD does crazy things to people and we all react differently.
