Hello, I’m 18 years old and have what seems to be a blood blister in the same region of my mouth for a few months now. It doesn’t cause any pain unless I poke at it, at which point it will get larger until bursting. It will heal and then go back to the way it was. I’ve experienced no other symptoms because of it and it doesn’t impact my life, other than being an annoyance. Should I get it checked out?
