Overview

There are several life-threatening causes of back pain, including spinal cord or cauda equina compression, aortic dissection, aortic aneurysm, vertebral osteomyelitis, epidural abscess, and metastatic cancer. These should be evaluated alongside other possible causes of back pain by carefully assessing the nature of the pain, and obtaining a thorough patient history.

 ==Overview==
-There are several life-threatening causes of back pain which need to be evaluated for first, which include; spinal cord or cauda equina compression, aortic dissection, aortic aneurysm, vertebral osteomyelitis, epidural abscess, and metastatic cancer. The other possible causes of back pain can be evaluated for by carefully assessing the nature of the pain, and obtaining a thorough patient history.
