Once or twice a year since sometime after I was married (and my CRPS started exactly a year after) I have gotten a sore throat. It usually starts with itching and burning and then over the course of 2-3 days progresses to completely losing my voice, which provides no end of amusement to my husband. After several days I begin to get my voice back and everything returns to normal. No doctor has ever determined why this happens or which disease I have that it could be associated with. At this point I try to shrug it off and let my husband have his chuckles. Although having an itching/burning throat makes me crazy! Feel better fast.
