Hi friend,
Welcome to Health Care Magic
You have not stated your personal habits, family history, or co-morbidities, even age, gender...which could have an influence on the diagnosis and outcome... The description of pain too is not adequate – the character, aggravating and relieving factors and so on...
The features do not point to cardiac causes / Most likely
Anxiety, Muscle spasm, Spine and so on... However,
heart disease must be excluded first, before others / You ought to see a cardiologist – get examined; get investigated...EKG / HOLTER (24 to 48 hour ambulatory monitoring) /
ECHOcardiogram / TMT (Treadmill exercise ECG) / LABORATORY work-up – may all be necessary for further assessment and assistance.
The treating doctor may suggest them depending on need, based on his assessment of the situation.
Take care
Wishing speedy recovery
God bless
Good luck
