Depression and Chronic Pain

The Connection

Depression and chronic pain frequently occur together. Up to 85% of people with chronic pain experience depression, and people with depression are more likely to develop chronic pain. The two conditions share biological pathways and each can make the other worse, but treating both can improve outcomes.¹
