severe pain information from trusted sources:
Discomfort in the chest that can range from mild discomfort to severe pain is called angina. Although chest pain can have many origins, true angina is a symptom of inadequate blood and oxygen supply to the heart, a condition most often due to plaque in the arteries (also called ischemic or coronary heart disease). The heart requires a steady supply of oxygen and nutrients from arteries on the surface of the heart muscle called coronary arteries. When deposits (plaques) build up within the arteries, the condition is called coronary atherosclerosis (also known as coronary heart disease or ischemic heart disease). These plaques contain fats and inflammatory cells, and occur more frequently in smokers, older adults, males, and people with diabetes, high blood pressure, and high cholesterol. The plaques narrow the coronary arteries, reducing the arteries' ability to supply the heart with blood. When the heart does not receive enough oxygen and nutrients, angina results.
Pain is an alarm bell! Natures way of saying something is wrong. Pain is a message from the body that it is having trouble in a particular area. Without pain you would remain unaware of any health problems and would never know when the body needed help repairing itself. Disease, injury, and strenuous activity may cause pain in the affected body part, signaling that damage has been incurred. It also signals you to rest the injured area so that tissues can be repaired and so that additional damage can be prevented. Pain motivates you to seek treatment as well. Some people are born with a rare neurological disorder that makes them insensitive to pain. Unfortunately, they do not experience pain when the incur various injuries such as burns, cuts, and fractures, or if they bite their tongue. Because they are unaware of the pain, they cannot prevent damage or seek fast treatment. Pain can result from a combination of physical and mental pain. Some people can tolerate pain better than others. In some people, pain is cyclical, pain produces anxiety and this anxiety intensifies the pain. Fear of the physical problem and anticipation of the pain can also heighten the pain. People with an uneasy mind will suffer more from chronic pain. If one knows why one is experiencing pain, one can tolerate it better.
