What is chronic pain?
Chronic pain is pain that lasts for weeks, months, or even years. It often does not ease with regular pain medication.2 Chronic pain can have a distinct cause, such as a temporary injury or infection or a long-term disease. But some chronic pain has no obvious cause.3 Like depression, chronic pain can cause problems with sleep and daily activities, reducing your quality of life.2
