Hello , thank you for choosing healthcare magic According to standards every chest pain should be considered of cardiac origin untill proven otherwise. I would like to know the nature of your chest pain , is it diffused or u can pinpoint it with your finger? If a patient with chest pain upon exertions comes to my clinic i would like to do exercise tolerance test also known as stress . This test basically records ecg of exercising heart Other common causes of chest pain include GERD Peptic ulcer disease Gallbladder stones chostochondritis If stress EKG comes normal , take PPI e.g omeprazole 40mg for Gerd which does present with cardiac like pain I hope my response was helpful Regards Dr.Shah
