Angina is not a disease, but a symptom of heart problems. Generally, angina results when a clogged coronary artery restricts the flow of blood to your heart. The pain may feel like pressure or squeezing pain in your chest, like indigestion, or pain may occur in your shoulders, arms, neck, jaw or back.
