Good evening, everyone! So, we pierced our daughter's ears two years ago and everything was fine. About a month ago, one of her earrings fell off during the night. I put it back on in the morning and ever since then, her earlobe seems to be constantly infected, specifically just one ear. I've been applying chlorhexidine, then tetracycline ointment, but it hasn't helped. I even started using Levomekol and it hasn't helped either. When I remove the earring, everything is fine, but when I put it back on, the problem returns. Has anyone else experienced this?
