I'm a teenager and I have a bump on my upper lip wich has been there for a long time (longer than 4 months). It started out looking like a pimple on my upper lip whith a white piont, so I didn't touch it thinking it would go away after a while, but it never did. There is no white tip now, but still seems to have a tip. Another one developed more to the right so I tried to pop it (the new one), and it did. I also tried poping the first one but it ended up feeling like I just pinched my lip, and nothing happend. Sometimes it the area where the bump is gets dry (like when you don't put lotion on your skin), so I just pick off the bits of skin. Other than that I don't have any other symptoms from what I can tell. It's slightly darker than my lip (not very much), and it hasen't spread or grown in size. It's not in my mouth so I don't have to roll back my lip to see it.

Is it from adulesence, can anyone tell me what it is, anything about it, what I can do about it?

Any help would be appreciated, thanks in advance.
