An infected ear piercing can also develop years after a person got the original piercing. Usually, the infections are minor, and people can treat them at home without complications. Touching the piercing too often with dirty hands or not cleaning the area can lead to infections.
Similarly one may ask, why would an old ear piercing get infected?
A piercing can also get infected if there’s too much handling of the piercing or the post of the earring is rough. An infection can also occur if unsterile instruments were used, if the person piercing your ears didn’t use gloves, or if the posts themselves weren’t sterile.
In this regard, why is my piercing hard and swollen?
A cartilage piercing creates an open wound. As it heals, it may look swollen, lumpy, or like a bump. In the days immediately following a cartilage piercing, the body’s immune system triggers inflammation and swelling to heal the wound, sometimes leading to a cartilage bump.
