My apologies for having a life and not being able to respond to you immediately on a Saturday night. Glad to see you’re willing to quack it up on a Sunday morning though.
This study says the risk of a serious adverse event, immediately or up to 7 days after chiropractic treatment, was low to very low. https://www.ncbi.nlm.nih.gov/pubmed/17906581
And this study found no evidence of excess risk of VBA stroke associated with chiropractic care compared to primary care. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2271108/
Holla back when you find that study that says chiropractors cause “so many” adverse events.
