How do you know when it's infected? What are the signs?
A piercing is infected when the discharge is either green or yellow. Also, if the area becomes swollen or inflamed again after the initial swelling has subsided. Any time you see green or yellow pus or discharge; you should see a doctor and get appropriate medical treatment. It won’t necessarily mean you have to remove your piercing; you may simply have to take a course of antibiotics. If the area becomes red and inflamed with red streaks radiating out from the area, see a doctor right away.
