Now there are 8 or 9 (one big one in the center, with little ones randomly around it, slightly spread out), they are only on
the underside of the tongue
soft, movable skin (not the gums). They are yellowwhite in color, and don't appear to be leaking any type of fluid. I went to the same oral surgeon yesterday and he says he doesn't know what it is, he said it's not canker sores because there's no red ring around them, he also described them as raised instead of deep.
