Thanks Gail,

Actually you are right about the yeast infection. He did say that he got some white layer on top of his tongue and the doctors said it is infection by yeast (sorry, i forgot to mention that in the last post). They gave him some cream to apply on the tongue but since he was on chemo that day, he did not apply the medication. I will ask him to use that now and I will tell him about Nystatin,Diflucan.

Thanks again for your quick response.
