Bump on inner lower lip. sometimes flattens.when raised (looks like it's filled with water and blood) it hurts because it pushes my bottom front teeth?

May be: May be a mucocele, a minor salivary gland with a blocked duct. If so it's benign, but size can cause tooth instability. Next time it flares up go see your Dentist. Many other possibilities, some of them quite nasty. Let a Dentist evaluate and treat or refer. Don't expect it to self-cure.

How long?: How long have you had this lesion? Just watch it. It should resolve on its own. Give it a week. If still present or becomes larger see the doctor. Also do not ever smoke!!!

Evaluation needed: It is impossible to tell you what this bump is without seeing it. An oral surgeon or a dentist can evaluate this and tell you what it is and the best treatment.

Seek trestment: A bump in the lip has to de diagnosed for proper treatment. It can be as simple as due to trauma bitting lip or a sore from a disease condition

Mucocele: What you describe sounds like a mucocele. These usually occur from trauma when the duct from one of the many tiny mucus glands in the lip gets damaged. The gland then fills up with mucous . These will sometimes go away after a while but often the gland must be removed.

Bump: Two things come to mind, one is a mucocele while relatively benign may need removal. The other is an infection which certainly needs treatment. Since we can't diagnose or treat you over the internet, see your dentist as soon as possible to determine what it is. You say it hurts so why not feel better sooner rather than later?

Mucolcele?: This sounds like a mucocele. These are caused by trauma and resolved with a minor surgical procedure. It could also be other more serious things. I recommend you have this evaluated by a dentist or oral surgeon asarp.

Mucocele possibly: The bump on the inside of your lip might be a mucocele. It is a clear bump filled with salvia. Caused when the duct to a minor salivary gland gets clogged and the saliva backs up, most often as the result of a minor trauma. They are most common on the lower lip but can occur elsewhere in the mouth. Usually they resolve on their own but sometimes large ones require surgical removal.

Possible Mucocele: Good day; Usually these soft swellings are harmless cysts known as mucoceles. They are mucus- containing cystic lesions of the minor salivary gland. Consider scheduling an appointment with your dentist to examine bump and discuss the necessary treatment.
