Chronic pain is considered to be pain that lasts longer than how many months?

Chronic pain is defined as pain that lasts longer than 3 to 6 months, rather than just 1 to 2 months as option D suggests. This is because chronic pain is typically characterized by persistent long-term discomfort that can significantly impact a person's quality of life, whereas pain that only lasts for 1 to 2 months may subside with appropriate treatment and is not considered chronic. Therefore, options A, C, and D are incorrect as they all provide shorter timeframes for what is considered chronic pain.
