What red flags raise concern for spinal infection or tumor in a patient with back pain?

• A. Night pain or constant pain that worsens at night, fever, weight loss, history of cancer, persistent neurological deficits.
• B. Pain that improves with rest and NSAIDs; no fever.
• C. Pain that begins after an exercise injury.
• D. No red flags present.

Answer: (B)

Night pain that persists or worsens at night, along with fever, unexplained weight loss, a history of cancer, and any new or ongoing neurological deficits, are signals that back pain may be due to a serious problem such as spinal infection or a tumor. Mechanical back pain typically doesn’t come with systemic symptoms and often varies with activity, improving with rest and simple measures. When systemic signs appear, they point to processes that can affect the spine from within—infection like vertebral osteomyelitis or an epidural abscess, or metastatic or primary tumors. A history of cancer raises concern for metastasis to the spine, while fever and weight loss support an inflammatory or malignant etiology. Neurological deficits suggest compression or mass effect on the spinal cord or nerve roots, which can occur with both infection and tumor and requires urgent evaluation. Therefore, the pattern described by the red flags is the most concerning for serious pathology and warrants prompt imaging (usually MRI with contrast) and appropriate labs (such as ESR/CRP, CBC, blood cultures if infection is suspected) and specialist referral. Pain patterns that improve with rest and NSAIDs, and the absence of fever or systemic symptoms, are more consistent with benign, mechanical back pain and do not raise the same level of concern.
