So a few weeks ago a bump appeared inside my lower lip. Since then it has gotten larger and a second smaller one appeared next to it and then grew until it was the size of the first. The bumps feel firm and look kind of clear or lightly colored buy are inside my lip and not on the surface so its hard to tell. They are both entirely painless and I can feel and move them through my lip or with my tongue. Could they be inflamed lymph nodes, pockets of fluid, or even cancer? What else is in the front portion of the lower lip that could cause this? I am only 18 and have never used any tobacco products so I doubt its cancer. I am also a virgin, so it can't be an STD.
