### Patient: Hi, doctor. I've been experiencing arm swelling, burning abdominal pain, and side pain. Do you know what could be causing this?
### Doctor: It sounds like you have an abdominal aortic aneurysm. This is a bulge in the wall of the aorta, the largest blood vessel in the body, which can cause symptoms like the ones you are describing. We will need to schedule some tests to confirm this diagnosis.
