Small bump inside upperlip. Answers.

So 3 days ago, i noticed a small lump above my upper lip. It is NOT inside my mouth, but inside my skin right above my top lip. It hurts to the touch and feels as if there is a small pebble inside. There is no head or any indication as for it to be acne because it looks just like my skin has a bump. Almost as if i would need it to get it removed, i would need to cut open my skin to remove whatever it is. Nobody seems to know what it is, but multiple people have it. I know 100% that it is is not a mucocele because again, it is NOT inside my mouth but inside my skin right above my top lip. It hasnt grown and it isnt very big, but it also hasnt gone away. I dont know if i should be worried or what to do, i need answers.
