Welcome to Neuro Talk. You will find alot of folks here with RSD. I have it also, or some kind of PN. From experience, I also know the pain meds themselves can make a person sweat and have chills. When I have a flair or a worse day, I tend to sweat. I think it is a reaction from the pain too. Check with your doctor about this more. Hope you get alot of response to your post. Glad you found this site. ginnie
