My mom always used rubbing alcohol to clean our ears and earrings... it burns if there is anything open... but if you are completely healed, it shouldn't. I had a terrible infection when little, and my mom got me some sleepers... the round ones that connect to each other and can go all the way through and rotate. I actually quit wearing earrings for years and then one day decided to try them again, although I thought they may have grown closed, and I could wear them! My earring holes are tiny (and kinda slit-looking) though. Good luck, and I hope your ears are completely healed for you.
