How do acute and chronic pain differ?

• A. Chronic pain persists beyond normal healing time
• B. Acute pain has a sudden onset and limited duration; chronic pain lasts beyond normal healing time
• C. Acute pain lasts longer than chronic pain
• D. They are the same

Answer: (B)

Acute pain is the body's immediate signal of injury, starting suddenly and lasting only as long as the tissue is healing. It serves as a warning that something is wrong and typically diminishes once healing progresses or completes. Chronic pain, on the other hand, persists well beyond the usual healing period. It often lasts months or longer and may continue even after the initial injury has healed, sometimes involving changes in the nervous system or ongoing functional and emotional factors. This distinction matters because it shapes how clinicians approach care: acute pain is usually managed to relieve immediate symptoms and support healing, while chronic pain requires a broader, multidisciplinary approach to address ongoing symptoms, function, and quality of life.
