Angina pain is most often localized to the chest, and the discomfort is typically described as a feeling of heavy pressure, fullness, burning, or squeezing. However, it’s not uncommon for the pain that you feel in your chest to spread to other areas of the body, including your jaw, shoulders, neck, back, and abdomen.  This spreading of pain is caused by lack of oxygen flowing to the heart and is known as “angina equivalents.” You may also experience fatigue, nausea, vomiting, shortness of breath, and excessive sweating a result of your angina pain.  It’s important to note that the severity, duration, and type of angina that you feel can vary. However, if you begin to experience symptoms that are new or different than what is normal for you, it may indicate that (1) you condition is worsening or (2) that you may be in the midst of a pre-heart attack.
