Before I realized I am sensitive to nickel, I would have to use peroxide to clear up the infections. Much better than alcohol. And tea tree oil is more effective and safer than antibiotic ointments and creams. Buy only pharmaceutical grade of tea tree oil, make sure it's in a brown bottle, and no double dipping. Use a cotton swab once, and if you need additional tea tree oil, use the other end or a new swab, as it's easily contaminated.
I can usually make it through the work day with my silver earrings, but my ears will be so sore the next day, I won't be able to wear anything. White gold gives me the look of silver without the problems.
