About two months ago I was sick and whipped my nose with a cloth, it cut my upper lip and I didn t treat it well, when it healed it left this dark patch of skin above my upper lip and below my nose in a arch around my upper lip, looks a lot like a moustaches, I left it alone and thought it would pass but it didn t and its not getting any better which is troubling me, I m a 13 year old black male.
