For months, I've had a tummy pulse, and general discomfort, combined with headaches, and occasional chest pain. This makes me feel that I have either an abdominal aortic aneurysm, thoracic aortic aneurysm, or even a brain aneurysm. Thing is, it's made me paranoid of lifting. I used to exercise a lot, but now I'm afraid if I do, I'm gonna rupture an aneurysm! What do I do?
