Not sure?

Hello people, glad i found this site and wanted some opinions before i called the doc. it seems to have been going on for a little while, i get usually just 1 at a time inside my upper lip, a clear little bump and it would go away after i broke it, usually about the size of a tip of a ball point pen. I only seem to notice i have one after i eat, but not sure exactly when it gets there.. this time i have a slightly bigger, almost the size of a pencil eraser.. but on the inside my cheek in the back, like near my last molar on the top- does it sound like mucocele to anyone??
