A few days ago, a female teacher in her 30’s saw me for back pain and was very happy with the results. When I was talking to her, she told me that her son, who had just started elementary school, had been complaining of eye discomfort for the past 2 years and had to blink rapidly from time to time, and asked me if I knew what was wrong. I asked her if she had ever had a detailed eye exam, and she said she had had all kinds of exams and had been ordering eye drops for 2 years, but they still didn’t work. I told her that if there was no problem with the eye examination, it was most likely a problem with the cervical spine. It dawned on her that in addition to blinking, he had to shrug his shoulders and shrink his neck a lot, saying that his neck was uncomfortable. I laughed and told her that that was even more indicative of a cervical spine problem. A while later, she brought her son from the ophthalmology department to my office. I had him take a cervical spine film, and then after detailed palpation, I found that the child’s second cervical vertebra was skewed to the left, and the 4th, 5th, and 6th cervical vertebrae also had a side-bending side-swinging misalignment. After Long’s technique was gently adjusted, the little patient immediately felt much easier on his eyes and did not want to shrug his shoulders. The family was amazed when the symptoms basically disappeared after continuing to consolidate the treatment for three more times thereafter. Cervical spine joint disorders can stimulate the vertebrobasilar artery, resulting in insufficient blood supply to the eyes, which can lead to dry eyes, blurred vision, and a tendency to blink. At the same time, it will lead to spasm of many muscles around the cervical vertebrae, and clinically there will be symptoms such as having to keep shrugging the shoulders, shrinking the neck, shaking the head and getting dizzy. All these are the trouble of cervical spine.
