My daughter is three years old and has had her ears pierced for eight months. Today she complained that her earring was bothering her, so we took it out and found that her ear lobe is extremely swollen, a bit purple, and has green/yellow/white puss coming out of it. She has had a cold, could the virus from the cold somehow spread to her earring? She does not have a fever, but has been complaining of a sore throat and runny nose.
