What is the primary symptom of an aortic aneurysm?

The primary symptom of an aortic aneurysm, particularly if it occurs in the abdominal section (abdominal aortic aneurysm), is often abdominal pain. This pain is typically described as a deep, constant ache that may be felt in the lower back or flank areas. An abdominal aortic aneurysm can be life-threatening if it ruptures, and the pain often serves as a major warning sign. It is important for individuals experiencing this type of pain, especially if it is sudden or severe, to seek immediate medical attention.

While chest pain can occur with an aortic aneurysm, it is more commonly associated with issues related to the heart itself, such as myocardial infarction. Leg numbness could be indicative of other vascular issues or nerve problems, and back pain, though it can be associated with an aneurysm, is not usually the primary symptom and is often nonspecific. Therefore, the focus on abdominal pain reflects its prominence as an initial symptom indicative of an abdominal aortic aneurysm. This understanding is critical for proper diagnosis and timely intervention.
