question: Good Evening, I am curious about an uncomfortable throbbing sensation in my heart (to the rhythm of my heart) after exercise (not during). It is not a pain but almost. I have had it for years and it is, I think, getting more pronounced but very slowly. A curious feature is that it will disappear for a few seconds when I shift my weight from one foot to another. If I am standing, it can last a few minutes. It is not there if I sit down. I don t think it is angina. In parenthesis, I am one of those persons who feels every heartbeat under normal circumstances.
