I have a pea size bump behind my right ear it causes no pain just wondering what it could be and if there is a possibility it could be from my teeth I have two broke wisdom teeth that I need pulled but just scared to go to the dentist I also have a small bump inside my left jaw it feels like it's in my cheek I can only feel it from the outside but also very small my wisdom tooth broke about 2years ago only felt the bumps about 6 months ago?
