Really? No one?
I actually have 2 spots -- one on my hard palate, close to where the soft palate starts, and another practically behind my front teeth. The spots aren't raised (as far as I can tell), but when I rub my tongue over them they have a raw feeling (not sure if that makes sense -- it's more of a taste than a feeling).
One has been there for over a week, and the other I noticed less than a week ago? The spots are pink/red.
