Contact a doctor immediately. Piercing infections cannot be countered by topical, over-the-counter remedies. Visit your doctor to have a proper course of medication prescribed. If your doctor is not available, try an urgent care clinic or your local emergency room -- infections should not wait.
Keep your jewelry in place until you can discuss the options with your physician. Removing the jewelry may cause an infected piercing to close. This can result in an abscess underneath the skin, trapping the infection.
Take a course of antibiotics as prescribed by your doctor. In order for antibiotics to be effective, the complete course must be taken without a break or early finish. Continue any piercing aftercare, if necessary, while antibiotics are being taken.
