While I was doing radiation I met with the radiation doctor once a week. So that was the chance I had to get those types of questions answered. Hopefully you see yours asap to help you get to the bottom of whether you have thrush or not. When my whole mouth peeled like that he went ahead and ordered me a script just in case it was related to thrush (I don't believe it was). But it's nice to have that reassurance that if it IS thrush, it's being treated.

As far as dry mouth, I haven't felt too affected so I don't have much by way of advice on that. My issue feels more like just having such thick saliva and it seems to have a way of hanging out at the base of my throat.
