Low back pain differential diagnosis
Introduction

Overview
Overview
Diagnosing the cause of back pain can be difficult, because many diseases can cause this symptom. Most frequently the cause is benign and/or self-limiting, but more serious causes may require urgent intervention. Acute back pain is a severe, persistent back pain of sudden onset that is likely to require surgical intervention to treat its cause. The following table summarizes differential diagnosis for back pain.
