Hi Sonyaparish69, I think you might ask your cardio MD if this was an accidental discovery as I have an ascending aortic aneurysm and I do not have any pain and mine is about the same size of yours. My concern is that the source of your pain is still undiagnosed. Just a good topic for discussion with your MD. I am not a medical professional so can't really say much other than to suggest you check it out with your cardio to assure your symptoms are not from another issue.
