Symptoms of angina include pain or discomfort in the chest, shortness of breath, and sweating, according to Mayo Clinic. Angina may cause some people to feel dizzy, fatigued or nauseous. Some people with angina may experience chest pain that may be accompanied by arm, jaw, neck, shoulder or back pain.
Angina may cause a feeling as if the chest is being compressed or squeezed, notes Mayo Clinic. It may also feel similar to indigestion. The most common type of angina is stable angina, which usually goes away naturally. It is important to seek immediate medical attention if stable angina worsens.
Stable angina usually occurs after exercise when the heart is pushed harder than usual, states Mayo Clinic. The pain tends to be familiar and is usually predictable. On average, it usually lasts less than five minutes, and taking medication usually makes it go away quickly.
If unstable angina occurs, it is important to seek medical assistance, according to Mayo Clinic. Some signs of unstable angina include having angina symptoms while at rest and a lack of relief after taking medication. If angina symptoms occur unexpectedly, or if they seem different than usual, it may be unstable angina. Unstable angina may last as long as 30 minutes, and the symptoms may be more severe than usual.
