Whats the best way to get rid of an infection in just the bottom hole of your bottom belly button ring?

If infected...: If you definitely think the area is infected you need to see a doctor for exam and possible oral antibiotic prescription if confirmed it is an infection. We cannot make a diagnosis of this issue through this platform without taking a look at it. Best wishes.

Consider this:: Clean with mild soap and water, and use topical bacitracin, two or three times a day. Keep it covered with a bandaid to avoid irritation. If no better in 3-5 days see doc. If fever, surrounding redness, increasing pain, get seen immediately. Hope it is nothing! Also, with any skin wound make sure your tetanus is current. If diabetic or have a serious chronic medical condition, see/call MD ASAP
