Syncopal (fainting) syndromes were linked to the cervical spine following injuries or irritations to the cervical spine. -Unterharnscheidt, F. (1956)
An example of this:
This 34-year-old male was hit hard on the head by his garage door. One month later, he woke up with severe pain in his neck and base of his skull, headaches, dizziness and fainting. He went to the emergency room and multiple tests were performed including MRI’s, X-rays, and a spinal tap. He was told that his tests were normal and he was prescribed heavy doses of pain killers including Vicadin, which did not alleviate his pain. After seeing a neurosurgeon, who told him there was nothing that could be done, he saw another neurologist, who prescribed more pain medications and steroid anti-inflammatories. His pain was rated as a 5 or 6 on the 1-10 scale daily and the pain medications weren’t working. He eventually sought help from a naturopath who referred him for an upper cervical chiropractic evaluation. At the time of his initial upper cervical chiropractic evaluation, he had suffered from daily neck pain, headaches, and dizziness for six straight weeks. During his evaluation, an injury in his upper neck was discovered, which had likely stemmed from the blow to the head by the garage door. Within a month of care, all of his pain, headaches, and dizziness were absent. Months later, his condition remained stable and no symptoms were reported.
