Hi NurseKris,
I have noticed being more sensitive to heat than before and like you was often cold in the past. I can definitely see our temperature regulation getting out of whack. My autonomics aren't what they used to be.
Sometimes I wonder if it is partly medication. I started flushing when I got hot after beginning nortriptyline. It was really noticeable early on. It could also be a combination of things....I think hormone fluctuations may contribute too and I am just more sensitive to a lot of things since CRPS.
Hope you are having a good day, stay cool my friend...
