No I don't think it is heart burn. I am beginning to think it is an actual sore throat. I am now feeling it all day. I have had a bad pain day. Tired and just plain icky more so than yesterday.

Hope you get to feeling better soon...sore throats can be so annoying

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.

I only had this happen once about 2 months ago & it was scarry
because I never have
experienced "heartburn" before & I'm 55. There was nothing different about
my diet that day. It has never happened since.

Yeah I never had heartburn until recently. I'll be 41 next month. The first couple times I was freaking out! It happens on and off now. I've found drinking some water to break down the acid helps and OTC zantac.
