OK, I have a bubbling sensation about 3 - 4 finger widths above my left nipple , usually when I am walking, I stop to try to feel it with my fingers and it stops, I haven;t been able to feel it on the skin, just inside, many times today too. No pain or discomfort. I have a re-stented stent in the LAD (1998 and 2009) and a second stent (2009), but in great shape, strss testes fine. This is new though.
