This is probably a minor infection that you could try treating at home unless the piercing is through cartilage. Cartilage is the hard tissue in the rim of the ear. Seek medical care for a cartilage piercing that is painful, itchy, swollen, and very red or dark. Color changes may be easier or harder to see depending on your skin color.

For minor piercing infections in soft tissue, take these steps:

• Wash your hands with soap and water.
• Apply a clean, warm, damp cloth to the piercing site until the cloth is no longer warm (usually about 15 minutes). Do this four times within 24 hours.
• Keep your phone clean and change your pillowcase every other day.
• Continue to follow regular aftercare instructions. This typically includes cleaning the area twice daily with soap and water.

See your healthcare professional if the skin color changes and swelling don't get better or the site oozes blood or pus. Pus can be white, green or yellow.
