If you notice swelling in your ear after getting a piercing, it is important to remove the piercing if there are signs of inflammation such as redness, pain, or swelling. Cleaning the piercing properly is essential for healing. For ear piercings, basic hygiene like cleaning with water and mild soap a few times a day is usually enough. It is advisable to stop using products like Polysporin as it can slow down the healing process. If swelling or pain persists after a week or gets worse, it is recommended to consult a doctor.
