How does angina feel?

Angina is most often described as chest pain, but this can be misleading. Angina isn't always painful. And it isn’t always felt in the chest. You may feel it in your chest, back, belly (abdomen), arm, shoulder, neck, or jaw. It might feel like:

  • Discomfort.

  • An aching, sharp, dull, or burning feeling.

  • Tightness or squeezing.

  • Pressure that comes and goes.

Other symptoms may include:

  • Severe tiredness (fatigue) that gets worse. Or you might feel more tired than normal for no clear reason.

  • Shortness of breath while doing something that used to be easy.

  • Heartburn, indigestion, or an upset stomach (nausea).

  • A rapid heart rate, or sweating.

  • Feeling lightheaded or fainting.

Call 911

Call 911 right away if any of your symptoms:

  • Last more than a few minutes.

  • Go away and come back.

  • Happen at rest and don't go away after you take nitroglycerin as prescribed by your doctor.

  • Keep getting worse.

You could be having a heart attack. Don't drive to the hospital yourself or have someone else drive you. Call 911 for an ambulance to transport you. The emergency medical technicians can start treating you right away.

When does angina happen?

  • Angina usually happens during activity. It can also occur when you feel stressed or after a large meal. Sometimes it can happen when the weather is too hot or too cold. All of these things can put more stress on your body and your heart.

  • You may have unstable angina if angina:

    • Starts occurring more often.

    • Lasts longer.

    • Happens even when you're resting, sleeping, or doing little physical activity.

    • Causes more discomfort.

    It’s a sign that your heart problem may be getting worse. Contact your doctor right away.
