it started last year, when i noticed a bubble inside my
lip, right by the front lower teeth. every day i was irritating it with my tongue, occasionally biting it. the bubble would disappear, then come back again. For once i decided not to brake it, but over 3 days it grew into a tight "water ball", which could resist all the biting, it actually increased in shape. My lower lip looked ridiculuoisly huge, everyone thought i had an infection even though it never hurt me.
