Fourth, hyperplasia and compression of the intervertebral discs stimulate the head, into the intracranial blood vessels of the nerves, causing vasospasm can also cause severe headaches. If accompanied by vomiting also need to pay attention to whether it is plant nerve dysfunction and cause severe intracranial ischemia, at the same time cervical spondylosis headache and vascular tension headache and vomiting, gastrointestinal diseases, reflux oesophagitis compression of the esophagus and neurological dysfunction, including cervical spondylosis stimulation caused by insufficient blood supply after the changes in blood pressure are related to need to be carefully analyzed and examined clearly, must pay attention to exclude intracranial lesions caused by the headache, Vomiting.
