Thanks Seth, I am glad to know that these are common after RT. I now remember I used to get them once in a while before the cancer was found. I usually push it against my tooth and pop the blister and then the feel better. But I can't do that with the ones in the back of my throat. Yes, they do hurt like a sore throat!

My sore spot on my tongue is close to a filling as well but I think my spot is where the stitches tore after surgery. They used alladerm (spelling?) and it tore away when I coughed...it healed but hasn't totally closed. It IS getting better tho so I am happy.

I do seem to have some/most taste back but dry mouth and blisters and chewing have made it difficult to eat too much so far. Ensure, chocolate milk, yogurt...going to try McDonald's french fries tomorrow tho!
