Dear I can understand your concern . I would like to suggest you that ischemic pain of cardiac origin or we call it angina has certain features typically it is not pain it s a discomfort . Usually retrosternal in location that is in mid of chest but left and right side are also very common with radiation to rt or left arm or to jaw.it get aggrevated on exertion and relieved on taking rest.but some time just sweating or extreme weakness fatigue and dizziness may be the manifestation . Before considering angina we look for certain risk factors such as male sex, age more than 40 but it is now common in younger age groups also ,smoker, hypertension, diabetes obesity , sedentary life style , dyslipidemia , family history etc. Diagnosis of angina is clinical that means it is based on history only.ecg echocardiography may all come to normal..so you can understand the importance of complete history and examination . In your case if you have few risk factors then you can undergo treadmill test..that can be helpful in making correct diagnosis . So maintain your blood pressure and discuss abt this with your cardiologist . Hope this will help.
