I am 34 year old vaccinated male. 2 days ago suddenly I felt sharp pain both sides of chest after taking dinner. The pain was coming and going (sometimes less pain sometimes more) for 2 hours. After 2 hours pain subsided and I slept. Next morning I  underwent ECG. My ECG was normal. But blood pressure was 140/100. I am checking my BP since 3 days. It was 140/100, 132/82, 130/100 last three days. I don't feel any pain in chest now but there is some discomfort. It might be psychological. But this blood pressure thing is giving me more stress as doctor said it's not right. Please advise which test should I undergo to rule out any serious heart ailment. My ECG was normal. I don't smoke or drink. My height is 5'5" and weight 71 Kg.
