Black spots spreading on inner bottom lip.
On my bottom lip when i poke it out. U can see alot of black spots spreading. If you were to take your thumb and pointer fingers. With the thumb being on the bottom of my bottom lip and pointer finger being on top of my bottom lip and pull my lip out. U will see alot of black discoloration. At first it wasn't alot now it seems to have spreadin all through out my bottom inner lip. I do smoke. Im not sure if thats why. But i wanna know what it is.
