It would very difficult to give you any opinion without seeing the lesion, but i would say that any sore that does not heal within 7 to 10 days should be examined.
sorry ignore the 'these two lumps are connected' thing.
i am only concerned about the small painless lump in my mouth.
dos not sound serious-- if the tooth hurts it may be an abcess drainage point called a fistula. but you should have it evaluated.
i hope not. whenever i searched google I always find that 'small painless mouth ulcer' means cancer...
that is pretty scary.
