"Chronic" and "persistent" pain are words that are often used interchangeably to describe pain that lasts for longer than 3 months. While the World Health Organization has recently added "chronic pain" to the International Classification of Diseases (ICD), some people with pain and health care providers prefer the term "persistent pain." In order to better understand how and why individuals and organizations use these words, Pain BC has put together a brief survey that should take no longer than five minutes to complete. Thank you for your participation.
