I haven't read the other responses, so this may be a duplicate. But what you are describing sounds like what happens to me when I'm about to get a cold sore! It starts in my mouth, where my gums get inflamed, then sort of moves up my face to where my eyes get puffy, then finally... cold sore on my lip. All of this is painful and will even cause achiness throughout my body and headaches. Definitely see you doctor one way or the other though, because even if it is a cold sore, they can prescribe an anti-viral medication (Acyclovir) that is inexpensive at the pharmacy, and will prevent the cold sore from even forming if you catch it early.
