There are logical answers to these questions. However if BOOPers refuse to pull themselves out of BOOPdom, they will never know the answers to these questions and will forever be resentful of non-BOOPers. They will continue to suffer from BOOP paranoia syndrome, and will never begin to appreciate the contemporary implications of this basic philosophical tenet of chiropractic. Figure A demonstrates a proposed mechanism by which nociception can result in pain, autonomic symptoms, vasoconstriction and muscle spasm. Vasoconstriction and muscle spasm can initiate and perpetuate the subluxation complex.
Vasoconstriction is an example of sympathetic hyperactivity.
The end result is reduced pain and reduced sympathetic hyperactivity. There are other people, called mothers, who have done the same thing. What seems to be going on is that these sort of people are able to plug into their periaquaductal gray. Note what is going on here. In these situations, a person has an experience that brings with it pain , but a part of the person consciously does something so that the pain is not felt.
