The pain involved to re-pierce a belly button will depend on the reason for the re-piercing, the condition of the tissue and the tolerance to pain; mild temporary pain is normal, states MDhealth.com. In order to prevent an infection, the belly button piercing should be done by a professional using sterile equipment. Signs of infection includes pain, redness or odorous discharge.
Belly button piercings need to be properly cleaned with a cotton swab and antibacterial or saltwater solution. A natural healing oil can be used to promote healing. Avoid changing the jewelry or frequently touching the area until fully healed. Healing times vary by individual but can take several weeks to months, notes MDhealth.com.
