In a patient presenting with severe pain at the base of the left big toe, which symptom most strongly suggests a diagnosis other than gout?

• A. Pain
• B. Elevated sedimentation rate
• C. Erythema
• D. Fever

Answer: (D)

Systemic signs help distinguish a gout flare from other serious issues. A gout attack is typically a sudden, intensely painful, swollen, and red joint without high fever. Fever introduces the possibility of infection, such as septic arthritis, which can present with severe toe pain and may look similar to gout but requires urgent evaluation and joint analysis. While an elevated ESR and erythema can occur with gout, they are not as specific, and pain alone fits gout. So fever most strongly suggests an alternate, potentially infectious diagnosis.
