“New research suggests that difficult experiences in childhood may prime the nervous system for chronic pain later in life. A study involving nearly 2,500 trauma survivors found that those with a history of abuse or bullying were more likely to suffer from persistent physical pain following a car crash or similar event in adulthood. The researchers validated these findings by observing similar patterns in laboratory rats. These results, published in the journal Pain, provide evidence that early life adversity is a biological vulnerability factor for poor recovery from injury.
Most people experience a traumatic event at some point in their lives. While the majority of individuals recover physically and emotionally, a subset develops chronic post-traumatic musculoskeletal pain. This condition is characterized by persistent soreness and discomfort that often continues long after physical injuries have healed. Medical providers have struggled to identify which patients are most at risk for this outcome.
The inability to predict who will develop chronic pain hinders the development of preventive treatments. Previous research has established that early life adversity can harm long-term mental health. Lauren A. McKibben, a researcher at the University of North Carolina at Chapel Hill, and her colleagues hypothesized that these early experiences might also affect physical pain processing. They sought to determine if childhood stress alters the body in a way that makes it harder to recover from physical trauma decades later.”
