Not as common an area for oral cancer. As an STD, it doesn't ring any bells for me but I don't treat STDs on a normal basis. I would recommend going to your physician and getting it checked out.
How did it get bigger? As in, you feel a bigger bump underneath?
I would also like to add that I am a heavy smoker if that matters.
I have just checked, it seems like it got a bit bigger now and I think it is under the skin, I am so scared what could it be ?
it doesnt change in size and doesnt pop anymore, the mark might still be there though im not sure because its too small, are there other things it might be other than mucocele ? like an STD of some sort ?
So it doesn't change in size or pop anymore? It might have been a mucocele. Its a small cyst-like thing on lower lips. Usually caused by biting on the lower lip, its due to a severed salivary gland. Usually you'll have a surgeon basically pop it and remove it so that it can heal properly. But it seems like you did it on your own. I would keep an eye on it and if there's any changes, I would go see your physician or dentist. When's your next checkup?
I think it is but it I too small to really notice , I think I might feel a shape , what could it be ?
Is the small bubble still there? Any current symptoms at all?
