I have a issue with my lip on top & bottom lip where there is a rash. or something & it turning my lip sort of black. Like blood is slowly dieing in my lips. I went to the doctor about it last month. He told me it was hair infection. may be from a razor. But that's not it. I take cephalexin 250 MG. That did not work! Then he gave ciprofloxacin 500 MG. That did not work. I was really scared too take the last one. But I prayed on it & it did not work. Can think of what I may have. I going to a derm. in the morning,
