This is one questions I;m still pondering. When I was younger I had a condition called Spondylolysis which is the precursor to Spondylolisthesis. Apparently 50% of all youth back pain is attrituable to spondylolysis. Meaning that 50% of all kids who report with back pain have spondylolysis but only 10% of adolescents have the condition. If back pain is attrituable to emotions then how come having conditions such as spondylolysis, spondylolisthesis and herniated discs make you statistically more likely to have back pain. I realize the counter argument is that only 25% of kids with spondylolysis are symptomatic.
