Author: Don Stader M.D. Educational Pearls: Non-traumatic back pain is a very common complaint in the Emergency Department. Conditions that can manifest with back pain include: ruptured abdominal aortic aneurysm, retroperitoneal bleeding, cauda equina syndrome, epidural abscess or cancer. Patients with cauda equina syndrome or epidural abscess prefer to sit forward, while people with disc issues tend to sit upright.
