Hello, thank you for your question!
First things first: if there is currently a discharge from the ear lobe, please take out the ear rings or loops to give the skin a chance to heal. The ear rings or loops are very good at attracting bacteria and letting them hide there and cause trouble.
For the moment, simply keep the area clean with soapy water 2 to 3 times a day. Do not put anything else on there. If the redness or discharge continues after 1 to 2 days, a medical evaluation will be necessary for a possible antibiotics course
As for the ear rings or loops, they also have to be thoroughly cleaned with soap and water as well.
I know you might be thinking if you take out the loops the hole will close. But if you keep them in, chances are the problem won't go away, and might worsen. Worst thing that can happen is the hole closes and the ears will have to be pierced again in a few months. This is a definitely better outcome than having an infection linger.
I hope I've been helpful, please do not hesitate if you have other questions
Tom Samaha, your friendly neighborhood pharmacist
