Chest pain can range from mild discomfort to severe pressure or tightness in the center of the chest. It may also spread to the left arm, jaw, neck, shoulder, or back. Because chest pain can be linked to heart attack, angina, lung disease, or gastric causes, fast medical evaluation is essential.
Warning signs that need urgent attention include chest heaviness lasting more than a few minutes, sweating, nausea, breathlessness, dizziness, or sudden weakness. If these symptoms appear together, treat it as a cardiac emergency and seek immediate care.
