My belly button has begun to protrude, and when i press on it it really hurts. what should i do?

Hernia: The most common reason for a protruding belly button is an umbilical hernia, a hernia is a condition where some of the contents of a body cavity protrude out from where they are usually contained. They can be painless but any hernia has a risk of trapping the contents. If a hernia is painful, it should be evaluated by a physician and repair considered.

Hernia: It is likely an umbilical hernia and an evaluation with a general surgeon is a good idea.
