I got a blister on the inside of my lip?

I was eating something..when i accidently bit a chunk it was red..but it didn't bleed or anyhing.. i only saw my teeth marks.. the the next day i felt kind of stinging then when i looked i saw that i got a blister...
now the 3rd day.. i notice that my lip swelled..
HOW DO I GET RID OF IT..

You have traumatized your lip and now it's trying to repair the damage. Don't worry, it just needs time. The general rule is that it takes 10 days for anything to heal in the oral cavity. Just be patient, and try to to bite or play with the part that is sore. If it is very painful, take an Advil or something that you normally take for pain.
