IMO it's the RSD. I went off Cymbalta last November and I sweat something terrible. When I asked my doctors they say RSD. Some people complain of freezing with RSD I get hot and sweat (mine is fullbody RSD). I do worse with my pain and symptoms in the summer. I live in OH we some nice warm days last weekend and early in the week. My body was red like a sunburn only I hadn't been in the sun the heat alone lights a fire to my body. I like the winter it keeps my body temperture down.
As one of my doctors and I like to joke it's my crazy short circuited nervous system.
Take care,
Sherrie
