Back pain with fever should raise suspicion for which etiology?

Back pain with fever should raise suspicion for which etiology?

• A. Infection
• B. Fracture
• C. Degenerative disc disease
• D. Muscle strain

Answer: (A)

Fever with back pain points to an infectious process in the spine. Infections such as vertebral osteomyelitis or discitis (and sometimes an epidural abscess) can present with localized back pain plus systemic signs like fever, signaling that bacteria may be involved. This combination requires urgent evaluation with inflammatory markers and magnetic resonance imaging of the spine, along with blood cultures, to confirm the diagnosis and guide antibiotics. Degenerative disc disease and muscle strain are mechanical problems and typically do not cause fever. They present with axial back pain that varies with movement and activity and lacks systemic signs. Fractures cause sharp focal pain, usually after a clear injury, but fever is not a characteristic feature unless a concurrent infection is present. So fever shifts the likelihood toward infection rather than these noninfectious causes.
