Swollen bumbs on his lips? NSFW just in case TW 🩸!

TW BLOOD!🩸 Well. I figured it was a mole or something and thought he was just against anyone touching his face. But this seems to be causing him pain and he has bled A LOT from this. I have no clue what this is from. We figured he may be biting himself when eating? They come and go so I don’t think cancer. But they always differ in size and placement around his jowls.
