If you suspect that your belly button piercing is infected, there are several steps you can take to treat it. Here are some tips from the search results:

1. Clean the area: Your piercing should be cleaned twice a day with an antibacterial soap. Use a cotton swab and your cleaning solution to gently wipe the area around your belly button and the ring. Pat the area dry with a clean towel.

2. Apply a warm compress: Place a warm compress on the infected piercing. This can help the pus drain and cause the swelling to go down.

3. Apply an over-the-counter antibacterial cream: An ointment with bacitracin (like Neosporin®) can treat the infection and assist in wound healing.

4. Dont remove the jewelry: Keeping the piercing in allows any pus to drain. If you remove the jewelry, you risk the wound closing up and trapping the infection inside your body.

5. See a doctor if necessary: If you feel like the infection is spreading and progressing, it’s time to see a doctor. Intense pain, swelling, or a fever can indicate a severe infection.

To avoid an infected piercing, clean it twice a day, avoid tight-fitting clothes, and soak the area daily. Its important to follow your piercers aftercare instructions and know the signs and symptoms of a possible infection.
