Has anyone had to deal with throat ulcers during or after chemo? I just finished my last round of chemo a week ago. Two days ago I started to develop mouth sores. I have used Biotine toothpaste and mouthwash during the chemo and have never had problems with mouth sores until now. But in addition to the mouth sores, now it feels like I have a sore throat and like something is lodged in my esophogus. My first thought was of course, "oh no another tumor" but I'm thinking (hoping) now it might be throat ulcers since the mouth ulcers developed at about the same time. I see throat ulcers are a side effect of the chemo and there is prescription medicine for it. Anybody else had to deal with this and have any thoughts on what can be done? The doctor is having me get a CAT scan tomorrow morning just to be sure nothing else is going on -- I think for my peace of mind more than anything else.
