I have a very small single hole like ir crater like spot inside my lip where the lip and gums connect it hurts when its touched or when i move my bottom lip around like when i smile. It didnt burn or hurt when i brushed my teeth and it kind of just appeared about 2 days ago and i just thought maybe i had cut my lip. I do smoke but lately i have been vaping on an ecig and have cut cigs out just about all the way now over the past 3 months i am also only 24 years old.
