Causes of chronic pain

Everyone experiences pain differently. Our thoughts, feelings and what is going on in our lives can impact how we experience pain.

For some people, pain has a known cause such as an injury, illness or surgery.

For others, the cause of pain is unknown.

Chronic pain is when pain lasts longer than 3 months. Sometimes, this happens because the brain misreads normal signs as danger, and sends pain signals to protect you, even when they aren't needed.

There are 2 types of chronic pain: primary and secondary. Chronic primary pain occurs when:

Living with chronic pain

Risks associated with opioid use for pain management

Opioids are medications that can be prescribed to manage pain. While they can have benefits, they also have risks, with sometimes potentially serious side effects. These can include overdose and substance use disorder (also known as "addiction").

Unmanaged pain is one of many complex factors contributing to the drug crisis.

Talk to your health care provider if you have questions about managing chronic pain with opioids and to decide if they're right for you.

What Canada is doing about chronic pain

In 2019, Health Canada established the Canadian Pain Task Force to advise on how to prevent and manage chronic pain. The task force delivered 3 reports over 3 years. The final report, An Action Plan for Pain in Canada, made over 150 recommendations, so that:

  1. people with pain are recognized and supported
  2. we can effectively understand, prevent and treat pain throughout Canada
  3. Canada can better meet the needs of people living with chronic pain in the future

The task force ended in December 2021. Since then, the federal government has made targeted investments to address their recommendations.

See the progress we're making towards these goals.

In February 2023, Health Canada and the Canadian Institutes of Health Research hosted a Best Brains Exchange. This exchange focused on treating chronic pain alongside mental health and substance use conditions.
