So I just had an echocardiogram done about two weeks ago and everything came back good, along with three good ekgs. But the other day I felt this random pulsating in my upper right abdomen and apparently thats you Aortic artery.it was right after eating and got it for maybe 25 mins on and off. Thinking back I have gotten it before and always feel a little weird in that area sometimes. I also do landscape work and when I rise the zero turn mowers to lift the deck up and down there is a pedal on the right side and my foot is constantly pushing it and its not "that" easy to press. Could that be why I feel the weird feeling on that side? I should also state I was always the type of person that fixated on every pain or sensation I felt. Anyway apparently the aorric anurisms run on my moms side of the family but I am only 22. Ever since hearing that I have been nervous and feeling that area constantly. Would the echo have picked up if I had an issue? I believe they put the ultra sound in that area as well but I was more concerned to hear my heart itself was OK.
