There is increasing evidence that supports an association between depression and back pain. A recent study published in Spine, February 2018, found that involved surveys and examinations of over 7,500 Korean adults found that individuals with back pain are almost five-times more likely to have depression. The findings suggest that clinicians should screen low back pain patients for depression so that appropriate treatment can be provided, which may even aid in the reduction of their back pain. Certainly it makes sense that if you are in extreme pain in a part of your body (lower back) that is involved in virtually every movement you make, depression, anger, and sadness are likely outcomes.
