I've never been to a spinal cracker and now I know why I will never do it again. I went in after a minor car collision, from which I was hit from behind, giving me whiplash. Dr Pinnix didn't x-ray or offer an MRI, nothing to see what damage or pre-existing conditions I may have had. He just put a warming blanket over my neck and then gave me the ole Navy SEAL neck breaker treatment!!!
This happened in 03 and since then my life with my neck condition has been absolutely miserable because of his negligence.
