Which statement best describes non-mechanical pain?

Which statement best describes non-mechanical pain?

• A. Pain that improves with changing position
• B. Pain that persists despite movement changes and may have systemic signs
• C. Pain limited to a single joint
• D. Pain only occurs during sleep

Answer: (B)

Non-mechanical pain is not tied to how you move or what position you’re in; it tends to persist even when you change posture or activities and can come with systemic signs like fever or weight loss. That combination—continuing despite movement changes and the possibility of systemic symptoms—best fits non-mechanical pain. Mechanical pain, by contrast, typically changes with movement or position and often improves with rest or a different posture, and it’s usually localized to a specific joint or region. The other descriptions point more toward mechanical patterns, so they’re less characteristic of non-mechanical pain.
