Welcome to the forum. Iif you have sensitive ears, you should be very careful about what you want to wear. You should chose those ear rings that are specially made for sensitive ears. Make sure if you can wear gold or silver earrings ( these do not cause allergy
and most people are fine wearing it) but check it out before you wear.
You should also avoid wearing it for a long time. Wear it before a party or when you are outdoors and remove it as soon as you get back home.
You should never wear it at bed time. It may expose your ears to inflammation or allergy. Some anti-allergic medication can be of help to you. But you should take it under the supervision of a dermatologist
and follow the doses strictly as prescribed.
Sometimes forceful wear results in a lot of complications like swelling in the entire affected ear lobe, redness
and inflammation, pain , soreness, discharge that can be clear but irritating. You may have to take oral medications or injections if the ears get pus and infection.
You need to study yourself. Wear what suits you best. Have a nice day, take care.
