Painless ulcer/lump on inside of lip.

[andydangerous]

I have an ulcer/lump on the inside of my mouth just below the bottom lip. It appeared suddenly then got smaller after a week and then stayed the same for another 4 weeks. I'm 28. Didn't think much of it until I did some googling, now starting to worry a bit. Meant to be going traveling on tuesday so not sure I can get to a doctor or dentist. Any advice would be appreciated.

Does it change in size throughout the day?  Any history of trauma to the area?  I'm initially thinking its a mucocele which is a bubble that forms when you bite your lip on accident and sever a salivary gland on the lip.  The fluid inside is saliva and tends to stay there and changes shape a little during meals (throughout the day).  Still, a biopsy would be best to find out what it is.

Hm.  Probably not a mucocele.  And they're painless?  I was thinking possibly a cold sore but those usually hurt and generally go away in a few days.  They can appear on the outside lips area as well as inside but usually not on the soft part of the lip but on the gums instead.  Probably a good idea to get a biopsy.  It may be just scar tissue from a previous injury

Also I do get alot of spots around the same area on my chin, on the outside of my mouth.

Haven't noticed it changing shape but I have been trying to leave it alone. It was alot bigger initially and appeared overnight. It is barely visible to the eye, just a bit of redness, but I can feel it with my tongue, it is in line with the top of my bottom teeth. Thanks for the fast reply.
