I also suggest that you call your physician so he/she can see you to find out what is causing the sensation.

I too have had a bubbling sensation above my heart all evening. Its very weird so thought I'd see what I could find out about it online. I have no history of heart - or any other major health problems at all. I do have gingivitis which I have heard can be related to stress and heart issues though.
