Removed nose ring piercing as infected and not improving despite cream and fluoxicillin. How can I now avoid abscess?

See doc. Whenever a treatment is not working or starting to work after 2-3 days, get checked again and/or call the doc today. You may be on the wrong medication or actually having problems from the meds. Creams can cause local reactions in some people and complicate the picture as it can be hard to tell if an infection is getting worse or the cream is causing increased symptoms not due to infection.
