If you or your child has symptoms of a paraumbilical hernia, you should talk to your doctor. Paraumbilical hernias are common in infants but should be looked at by a doctor to make sure there are no complications with the hernia. If the hernia bulge changes size, becomes hard, or more painful, seek a doctor immediately. These symptoms signal a complication with the hernia. Although complications are rare, it is best to have a doctor take a look. Surgery may be necessary to treat a paraumbilical hernia that has become incarcerated or strangulated.
