Which of the following terms refers to enduring pain that does not decrease over time?

Chronic pain is defined as pain that persists over a long period of time, typically more than three months. It is characterized by its enduring nature, often continuing well past normal healing time and sometimes occurring without a clear, identifiable cause. Individuals experiencing chronic pain may deal with ongoing discomfort that can vary in intensity and can significantly impact their quality of life, daily activities, and mental health.

In contrast, acute pain is a type of pain that comes on suddenly and has a specific cause, often linked to injury or illness, and typically resolves as the underlying issue heals. Deferred pain usually refers to pain that is felt at a later time after an event, rather than being a continuous experience. Temporary pain describes transient discomfort that is expected to resolve quickly, usually in response to a clear cause, like a sprain or strain. Hence, chronic pain is distinct for its long-term presence and complications that arise from its persistence.
