I got my piercing a month back and in the 4th week there was infection on both earlobes. The boils had pus however with certain medication and care the left ear became better but the right ear has a bigger boil with had a pus and now looks dark red or almost black because of blood. The bump is both in front and back of the right ear. Why is the bump/boil so dark and filled with blood They don't pain but might itch for few seconds after washing. Currently I am putting S -Clear ointment
