Back pain, a common complaint familiar to all physicians, can be either a manifestation of musculoskeletal dysfunction or a symptom of a more serious underlying disease. Unfortunately, the diagnosis can be difficult, and back pain that is not resolved by conservative treatment requires aggressive investigation.
