Hello and thank you for using HCM. I carefully read your question and I understand your concern. I will try to explain and give you my opinion. We talk about hypertension if we have mean values that exceeds 140/90 mmHg. Hypertension is divided in two groups: essential or idiopathic hypertension without an identifiable cause and secondary hypertension, usually in young ages, meaning that is a secondary cause of it. This cause might be a renal disease, an endocrine problem, a cardiovascular pathology. Essential hypertension is a chronic disease. It has not a definite cure, but it should be treated life long. Sometimes a lot of people does not feel anything even having high blood pressure. But sometimes, excessive blood pressure in a hypertensive crises can be manifested with headaches, blurred vision, nausea or vomiting, increased heart beats, chest pains or pressure as you describe. So, first of all i will recommend you to measure your blood pressure.If you have elevated values, meaning mean values above 140/80 mmHg than you have to treat it. If you leave your blood pressure untreated it slowly modify the heart. If I was your treating doctor i will recommend a full cardiac check up with blood test analyze, a electrocardioram, echo-cardiography, a pressure and rhythm holter monitoring. Only after this we can be able to judge to start a medication or not for high blood pressure and heart rates. In mean time avoid excessive salt intake, caffeine products, energy drinks.They rise your blood pressure and your heart frequencies. Hope I was helpful. Wish you good health. Best regards.
