HI i went to a dentist and he said i have a little lukoplakia (excuse my spelling), but thats not what im asking about. On my left side, very back muller, on the inner gum, underneath but not on my tongue, i have a small hard bump, well kinda hard, im afraid to push on it. when i touch it , it doesnt feel like a circle bump, but a oblong bump attached to a line. to get a better picture, think of the shape of a single sperm, or a shooting star. a bump with a tail. Nothing hanging of the gums or anything just underneath. The tail part of the bump is a bump also and it heads towards my throat but is only about a pinky nail long and about a centimeter big. A side note, I smoke marijuana, and ten cigs a day.
