Angina is chest pain or discomfort that occurs when your heart muscle doesn't get enough blood. Angina may feel like pressure or a squeezing. It can be mild or it can be severe. The pain may also occur in your shoulders, arms, neck, jaw, or back. You might not even have pain, but an unpleasant feeling in your chest and be short of breath. It may feel like indigestion.

If you have chest pain that lasts more 10 minutes call triple zero (000).

Angina usually occurs during exercise or stress. When it occurs at rest, perhaps even while your sleeping, and gets worse over time it is called unstable angina.
