question: When I lay down on my back for a while or durring the night my chest feels heavy and full. I cant lay for very long in this position with out it start being very uncomfortable. Sometimes I get some sharp pains in my chest that come and go. Also have a cough that is dry and random. I have had PVC diagnosed by a cardiologist. I also have high blood presure. Lately around 150/85 Just trying to see if the pain and heaviness in my chest is related to my heart.
