Thank you for the information Brian. I figured the burning was part of it all but it makes me nervous to have the sore spot. It looks as if one of my taste buds is swollen and the "stuff" on it has the same appearance as the sores I had during radiation. I haven't had any on my tounge for about a month now so was surprised. This is the second day it's been there. I found it yesterday when my tounge felt sore, I was surprised how quickly it appeared. Then by mid-day the "coating" on it was hardly visible and I couldn't really see it. When I got up this morning it was coated again but now, at 2:30pm, I have to look close to see it. Guess I will wait and see what it's like on Monday. In my mind I know it's mucositis/irritation. But my paranoid side is convinced it's cancer on my tongue. I hate what cancer does to a rationale mind.
