I have full-body RSD that started in my rt.foot. I too have it in my face and chest area, but not as extreme as you. I get a sunburned like feeling all over and when I cry, it feels like acid running down my cheeks. Everyone, including my dr's, thought I was crazy when I told them this. I also lock my jaw a lot, which I hear is related to RSD. I have a new symptom everyday sweetie, it stinks.
Plus, I just started taking Prozac 40mg. Not by choice, but I just had a baby and RSD has made me soooo emotional. I cry all the time over anything. It has really affected my life negatively.
Keep me posted on your situation. I am very interested and concerned for you on how it turns out. I wish you the best of luck hun!
