Thank you first of all. When I went to bed last nite, my lip was fine. No kissing, didn't bump into anything but….I woke up with 1/2 my bottom lip purple. I have no numbness, no tingling, no bumps, no discolor on the i/s of my lip. What can it possibly be. I've been online looking into possibilities and nothing seems to compare. What say you? P.S. I'm a male and it's not wine and can't be lipstick.
