Which symptom is commonly associated with inflammatory back pain?

• A. Alternating buttock pain
• B. Pain worse with rest
• C. Onset after age 60
• D. Pain improving with rest

Answer: (A)

Inflammatory back pain often involves the sacroiliac joints, and a hallmark clue is pain that can alternate between the buttocks. This alternating pattern reflects intermittent inflammation of either SI joint, which is typical in axial spondyloarthritis and other inflammatory conditions. While inflammatory back pain can also show morning stiffness that improves with activity and may worsen at night, the side-to-side buttock pain specifically points to sacroiliac involvement and helps differentiate it from other types of back pain. Onset after age 60 is atypical for inflammatory back pain, and while some inflammatory patterns can be worse with rest, the key distinguishing feature here is the alternating buttock pain, which more strongly signals an inflammatory process affecting the SI joints.
