For about a month now i have had a small bump on my cheek at the very back. It is right in between my wisdom teeth. When i first had gotten the bump my teeth had felt weird they didnt bite together pr\operly and it was kinda painful to bite down. The bump did felt like fluid was in it but it had gotten flat n sometimes it gotten back full again. But now the bump has an imprint of a bite mark on it but this thing is not going away. If you look at it closely it kinda looka like there is a hole in it. I'm 19 years old and I have been smoking for about 5 yrs so i am terrified that i may have cancer. I had an oral surgeon look at it and he told me it was nothing but biting from my wisdom teeth but i feel like it more than that. But before this bump had came up about a month b4 that my lymph nodes were irritated making it difficult to swollow along with weird nose bleeds that only happened about 2 times and i went to a doctor about that problem but she just gave me antibiotics and then it went away. Now along with the bump in my mouth it feels like my glands under my jaw are swollen!! Are these doctors playing around with me?? What is this??? Is there anyone out there experiencing the same or similar symptoms???
