Studies have shown that chronic pain might not only be caused by physical injury but also by stress and emotional issues. In particular, people who have experienced trauma and suffer from Post Traumatic Stress Disorder (PTSD) are often at a higher risk to develop chronic pain.
Stress and Back Pain. There is a strong connection between stress and back pain. Stress causes a release of stress hormones. Stress hormones increase the perception of pain. Stress hormones also cause the muscles to tighten up. The muscles may tense up so much they go into painful spasms. Muscle tension reduces blood flow to the tissues (reduced oxygen and nutrients to the tissues).
