I am wondering if most people are familiar with a word, angina or angina pectoris.
Angina is a medical condition associated with myocardial ischemia, and commonly develops on exercise but can occur even at rest. During an attack of angina, you feel discomfort in the chest.
Most people, including medical staff, consider chest pain a typical symptom in patients with angina, but it is likely to be a stereotypical misunderstanding. According to my patients who are diagnosed with angina in my hospital, the symptom is different form chest pain. They say it is not painful but oppressive; it could be expressed as a toothache or headache in some cases. Remember, symptoms associated with angina vary depending on the patient.
My recommendation is that you do not have to make a diagnosis. Given the relatively high mortality of patients with angina who are not appropriately treated, you should consult a cardiologist, especially if you have some risk factors, such as diabetes, hypertension, dislipidemia, smoking, and a family history of heart disease.
If symptoms last 15 minutes or longer, special attention should be paid because it may suggest more unstable conditions, such as myocardial infarction. You have to visit the emergency department as soon as possible.
