If your ear piercing is infected (redness, discharge), the best course of action is to remove the piercing completely for a few days to allow your ear to heal. Your body is reacting to the presence of the piercing, so it's important to wait until the infection has cleared before reinserting the piercing. After removing it, you should wash your ear with a mild soap around 2 times a day. If the redness and discharge do not improve within 3 days, it would be best to seek medical advice. Using Polysporin™ may not be effective in this case, as it is more for preventing infections rather than treating them. Additionally, if you have been using it for a while, the bacteria may have developed resistance to the antibiotics in the cream.
