How do you tell if a gauged ear is infected?

If you find that the tissue around the piercing is swelling, red, hot to the touch, painful or if there is unusual secretions, there is a very good chance of infection. You should remove any piece of jewelry, and clean the affected area with antibacterial liquid soap and lots of warm running water. Use this also to clean your jewelry. If symptoms do not go away within 24 hours you should see a medical professional.
