I don't consider so, but even if it can at hand is another key problem that desires to be ruled out first. You could be have a heart attack or angina. You don't articulate how ancient you are or whether you own risk factor for heart disease (diabetes, glorious blood pressure, smoking, cholesterol, line history), but citizens go and get heart disease even contained by the unreality of set risk factor.
When part of the pack or adjectives of the heart is denied passable blood supply, it does various things to try to upgrade the situation. One is, as luck would have it satisfactory, to try to time harder, which can in fact worsen things.

This bottle is a so-called autonomic fortitude, which ability that signals going from the body to the brain are not impressively specific, as would be the luggage next to somatic sensory nerves. The latter speak "Pain here" or "heat/cold here" and relate you exactly where on earth the stomach-ache is; that's how you can inform where on earth the pin stuck you accurately. With autonomic nerves, sometimes the spasm is missing, sometimes it's shifty (again, similar to nausea), and usually you can't make clear to where on earth it's coming from, which is why heart backache sometimes comes from the chest, but sometimes seem to be coming from the other shoulder, the collar, the mouth, or down the arms. Many heart attacks are "silent", purpose they don't create agony you sanction, a moment ago nausea, sweating, shortness of breath, or something else.
