Chronic pain duration criterion is...

• A. Greater than 3-6 months
• B. 1-2 weeks
• C. 1-2 days
• D. 12 months

Answer: (A)

Chronic pain is defined by how long it lasts—ultimately lasting beyond the normal healing period. In clinical practice, the boundary is usually around three months, with some definitions extending to six months. This makes the duration criterion of greater than 3–6 months the best match, because it captures the transition from short-term (acute) pain to pain that persists beyond the expected healing window. Shorter timeframes like days or weeks describe acute pain, while a year of persistent pain, though possible, still fits under the overarching idea of lasting longer than normal healing time; the threshold most commonly used is the 3–6 month range.
