What is Angina? How do I stop it?

Angina (an-JI-nuh or AN-juh-nuh) is chest pain or discomfort that occurs when an area of your heart muscle doesn’t get enough oxygen-rich blood.

Angina may feel like pressure or squeezing in your chest. The pain also may occur in your shoulders, arms, neck, jaw, or back. It can feel like indigestion.
