Internal Mouth bump?

Hello.
I am prone to canker sores on my bottom lip, but I seem to own a painful bump elsewhere.
Inside my mouth, similar to at the back, I can grain this one "wiggly" bump (if I could compare it to anything, it's like the bumps you obtain when you shave). When I touch it with my tougue, it hurts; I have it for like three or four days.
Is it a canker sore or something else?Internal Mouth bump?
Wash your mouth out near warm river an salt for 30 sec three times a daylight. now if it bust dont swallow it, you can bring sick or die. Make sure you brush good an use mouth bathe to keep this from happenign again
