Hi. Everything was fine then all of the sudden under my tongue started hurting i think a gland or something, then it started hurting in the back right under the tongue. I got up to look in mirror then a instant sudden lump started forming under my chin on my neck throat area. It feels like a tumor but would think tumor just doesn't pop up. the lump feels like it goes down then come back i think. It hurt to open my mouth but that kinda went down. What could this be.?
any anwers would be appreciated
