does it only happen to me?

why is it that when i accidentally bite my own tongue or lip etc. i tend to bite the same place over and over again? now not only can i not eat properly or talk properly because it hurts, i'm feeling puffy! plus i'm feeling bloated. at first i was wondering, why am i feeling bloated? not like i ate a lot or anything like that? then i realised, because of that stupid ulcer/bengkak, my salivary glands is over-producing saliva! stupid me! wanna know how i look like? imagine...puffy cheeks and bloated tummy! ahaha! how to make the pain go away?
