Once I got so badly drunk that I fell on the side walk, hit my lip and broke it. There was blood all over, and my lip swell instantly. I didn’t care much that night, but after a few hours when I left a club (it was already morning), it was burning like hell.
I went home and fell asleep. The lip was swollen for another day but it didn’t hurt anymore. The third day it was gone. I didn’t do anything to make it go away.
I suppose you friend will have a similar experience.
