Angina Pectoris (‘ strangling of chest’) is a recurring discomfort. It usually lasts only for a few minutes. In most cases, it occurs in the centre of the chest behind the breastbone. Angina has been described as heaviness, tightness, oppressive pain, burning and pressure or squeezing. Sometimes it spreads to the arms, neck or jaws. It may also cause numbness in the shoulders, arms or wrists.
