I was reading your post and your symptoms made me think, ecspecially the part about coldness... I have TOS and RSD... Now, I dont always know what symptoms are from what but i can say that i have RSD in my face it often affects my face with coldness, burning and general pain.... I would take a look and speak with you doctor about your symptoms... The coldness was the part that caught my eye.... My right arm is also effected by coldness.... Tempture change from my research is not a symptom of TOS.... I would defintaly consult with a doctor before your surgery! By the way good luck with your surgery i hope that it helps elevate some pain!!

Pain free days and gental hugs!!!
