A surprising discovery at UC San Diego suggests that chronic lower back pain may become deeply embedded in the brain’s sense of personal identity. Researchers found that movement-triggered pain activates a brain network associated with self-awareness and memories, even though ordinary acute pain typically shuts this network down. This unexpected difference could explain why conventional pain medications often provide limited relief and why fear, anticipation, and past experiences can intensify chronic pain.
Scientists discover why chronic back pain feels so personal. Now, scientists have discovered that these painful episodes activate a surprising part of the brain, one closely connected to our sense of identity and how we think about ourselves. Researchers at UC San Diego School of Medicine found that movement-triggered pain in people with chronic low back pain (cLBP) activates a brain network that normally becomes less active during ordinary pain.
The discovery suggests that persistent back pain may become deeply intertwined with a person’s sense of self, potentially helping explain why conventional pain treatments often provide limited relief. According to the World Health Organization, low back pain is the leading cause of disability worldwide. When pain persists for more than 12 weeks, it is considered chronic.
