I have emphysema which has caused right side ventricular heart failure with cor-pulmonale, I have mild twinges on the left side of chest, they are stronger with exertion, but can feel movement when sitting still. I become short of breath with very little exertion, tire easly
Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should rule out left sided heart failure in your case. Right sided heart failure and cor pulmonale can lead to left sided heart failure. And this can cause left sided twinges, breathlessness on exertion and tiredness. So get done ECG, 2d echo and stress test (trade mill test). You may need diuretic Chat Doctor.  Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
