Your symptoms could indicate something other than an abdominal aortic aneurysm.

• Nonspecific symptoms of mild abdominal pain or fullness or more severe abdominal pain could caused by peptic ulcer disease, gallbladder disease (gallstones), gastroesophageal reflux (GERD), pancreatitis, chronic mesenteric ischemia (narrowing of the arteries to the intestines), a kidney infection (pyelonephritis), or gastric, ovarian, or pancreatic cancer.
• If a cold foot or black toe is present, other possible causes are atrial fibrillation, peripheral arterial disease, or diseases of the heart valves.
• A pulsating mass in the abdomen could be a tumor, but this is rare.
