The pain in the left side of the chest comes when sleeping on the left side of the body and changes the subject of pain from day to day and comes in the form of pulses for 5 minutes and then disappear, and sometimes I feel shortness of breath at night
Thanks for your question on Chat Doctor. I can understand your concern. You are having recurrent bouts of left sided chest pain and occasional breathlessness. So possibility of heart related diseases like heart failure or coronary artery disease (CAD) is more. So better to consult cardiologist and get done 1. Blood pressure monitoring 2. ECG 3. 2d echo 4. Stress test (trade mill test) 5. Coronary angiography (if required). You may need diuretics and other cardiac supportive Chat Doctor.  Don't worry, you will be alright. But first diagnose yourself and then start appropriate treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
