Abdominal Aortic Aneurysm?

I have a very strong pulsing through my abdomen. The beat is constant, doesn't matter if i am sitting or standing, lying down, etc. it is always there. Occasional pain in the abdomen as well but this could be unrated, it is a sudden sharp or push, but again it could be something else. If it is a Abdominal Aortic Aneurysm there should be a sound along that artery right? I am use to listening to livestock medical uses through a stethoscope and I am wondering what specific sound I should look for? to determine if I should seek medical help for this constant pulsing? or is this just me? I have heard many mixed opinions about a 'heart beat in the stomach' and honestly I don't have access to doctor care easily. If i can rule it out myself via listening to it, I can literally save days of time and money. (yeah my doctors are that far away and yes I am really rural living.)
