So do I!: So do I on my index finger! This is completely benign (not a health problem at all) and has nothing to do with your previous biting habits. Think of it like a freckle or a discolored hair. It is made the same way by the nail cells right at the quick. They put dark pigment (melanin) into their growing nail and it extends as the nail grows. Think of it as just making you more unique and special!
