What can you do about sore ears when putting in earrings?

You either have infected ears, or you have a nickle allergy. If your ears are sore because of wearing too heavy earrings, it's a matter of wearing studs or very light earrings until the ears heal.

In the case of a nickle allergy, you must wear the "good" earrings of either silver or gold. Coating the posts or wires of the offending earrings is only a temporary fix. Check your backings too. They may be the culprit.

Infection is another reason to have sore ears. Look at your ears and see if they are red and/or swollen. In either case, using medicinal peroxide on them will help heal the infection, just like when you were caring for the holes when you first got them pierced.

Clean your earring in that peroxide, then put them in. This won't instantly cure the problem, but it will help. If the soreness persists for more than a day or two, see your doctor for the cause of the pain. Yes, it is important.
