My two year old got her ears pierced yesterday and the redness went away almost right away. And they look completely normal no signs of infection. She says they don't even hurt. Except today she started throwing up and having a high fever. I'm starting to worry. Should I call the doctor and ask if it could possibly be related to her piercing? Her fever keeps going up and down.
