Hi friend,
Welcome to Health Care Magic
The limited information provided is not sufficient enough to arrive at an appropriate conclusion and further suggestion... / You have not stated your personal habits, family history, or co-morbidities, even age or gender...which could influence the diagnosis and outcome...
Your symptoms do not suggest Coronary
Artery Disease (CAD) – pain from the heart is oppressing, in central chest (and left), worse on effort, relieved by rest, may radiate to shoulders and arms, associated with sweating and so on.
You need examination and investigation...
Take care
Wishing speedy recovery
God bless
Good luck
