I have had this red bump about the size of a large pea on my upper lip for a little over month now. Im a 16 year old male. I have already been to the doctor and they said it was a bacterial infection called impetigo.. they gave me antibiotics but they did not work. Im getting frustrated looking at this every time I look in the mirror at this thing. It isn't painful and the bump is small but it looks raw and red. Does anyone know what this might be or if they had something similar?
