When i was a baby i bit a cord on the side of my lip. was left with a scar that got bigger the older i got. I recently went to get the scar revised. Before surgery i was told that results could be worse & nothing else..It's been 2 1/2 weeks since surgery and i can't smile. My face & lip still feels like the anesthesia is wearing off. Theres also dropping & swelling of upper lip but not where the scar was removed. Could i have nerve damage? Is this normal? will swelling go away? Y do i drool?
