Chiropractors have known for many years that patterns for spinal issues tend to run in families. According to a 2011 study in The Journal of Bone and Joint Surgery, having a close relative with history of degenerative disc disease- a common change in the spine that is an underlying issue contributing to low back pain and sciatica- QUADRUPLED your chances of having the same issue. Unfortunatley, even a distant cousin with the condition still increased your tendency for the issue.
This is all the more reason that parents with back issues should start their kids on #chiropractic care EARLY to help balance the risks.
