Thank for the replies gentlemen.
As Dr. Erfani stated, this is most likely a mucocele, a single clogged tiny salivary gland. However, once surgically removed the SAME gland can never reclog, since it is gone. Therefore, you have another one, even if it seems the exact same place. You have thousands of tiny glands in your lip. You may be best treated by another removal. You could get another one later, but that would be unusual. Good luck.
I was hoping it would go away on it's own but it just sits here. So what do you think I should do?
This is called Mucocele. This can come from lip biting, other habits, or on their own. There is not much you can do about it and they usually go away on their own even if not removed surgically.
