Pimple like thing on back of throat?
I have had for about 6months(well this is when I first noticed it, so who knows how long it has been there) a sac like pimple on the back of my throat. It doesn't change size and there is no pain with it. I have even poked it and feel nothing. It is not going away and I am scared of what it is. I don't have any pain at all with my mouth or throat. It is about the size of the tip of a coloring crayon. What could it be?
