When you first get your ears pierced, the piercing technician inserts starter earrings. These earrings are made from hypo-allergenic materials that are safe to keep in your ears. Leave them in your ears both day and night for at least 4 weeks or your piercings may close or heal improperly. The hypo-allergenic earrings should be made of surgical stainless steel, titanium, niobium, or 14- or 18-karat gold. If you get a cartilage ear piercing, you will need to leave the starter jewelry in for 3-5 months while it heals fully. Unnecessary handling of your piercings can lead to infection. Avoid touching them unless you are cleaning or inspecting them. If you do need to touch them, wash your hands thoroughly with soap and water first. Swimming can lead to a transfer of bacteria to your new piercings, resulting in an infection. Steer clear of pools, rivers, lakes, and other bodies of water while your ears are healing. If you use a hot tub, avoid submerging your body deep enough in the water to get your ears wet. Keep your clothing away from your earrings while they heal. Pulling or friction can cause irritation and slow down the healing process. Avoid wearing hats that cover your ears and be careful when getting dressed and undressed to avoid injury. If you wear a veil, choose a fabric that won't snag easily. Try to wear very loose veils and avoid wearing the same veil multiple times without washing it. If your ears are painful and swollen a week or more after you get them pierced, they may be infected. Visit your doctor to have them checked if you notice pus or thick, dark discharge. Infected skin around the piercings will also likely be red or deep pink in color. Serious piercing infections may require drainage and oral antibiotics.

Summary:
Leave your starter earrings in your ears for at least 4-6 weeks. Always wash your hands before touching your ears. Avoid swimming while your piercings are healing. Be careful with items of clothing that could snag on your earrings. See a doctor if you notice signs of infection that last several days.
