I am thinking that my mom has thrush. She has a big white blotch on the front part of her tongue. She just finished radiation 2 weeks ago and her mouth is healing ok. She showed me her tongue and the blotch is probably 4 cm or so and oddly shaped and a looks kind of like a blister. She is seeing her oncologist on Friday so I'm sure she will let her know what it is. Also she really wants to drink or should I say swallow a big glass of water and she can only sip so its frustrating for her because she is so thirsty. How long before she will be able to drink and not sip?
