4. Random Pain
There are some people who will simply experience random pain when they have angina. When the pain occurs randomly it is possible that it is a sign of unstable angina. Unstable angina is more dangerous than stable angina and if you are suffering from this it is important to seek medical advice as soon as possible.
When most people think about chest pain they think about the severe pain that sends us straight to the emergency room. However, any pain in the chest can be quite serious. Pain that is caused by angina often will feel more like a cramp. It can also feel like a slight constriction.
With angina, your heart is attempting to do more work and the pain is caused by this. Even if the pain does not feel too bad and may not last for long, it is still important that you take it seriously.
