A couple of days ago, when she returned from her vacation in Hainan, my mother said she was dizzy from time to time, especially when she sat up in bed or turned over and felt spinning around. I don’t know what the problem is. The more common causes of dizziness and vertigo are cerebrovascular, inner ear or cervical spine disease, but the three should be distinguished. Patients with vertigo caused by cerebrovascular lesions will generally be older and should last longer and be less affected by position changes, and some will be accompanied by symptoms such as numbness in the hands and feet and weakness in both lower limbs. If the vertigo is simply after a change of position, such as lying down and suddenly sitting up, sitting and suddenly standing up, or lying down and suddenly turning sideways, etc., and the vertigo lasts for a short time and is sometimes light and heavy, after excluding the cause of otolith dislodgement, you should consider the possibility of cervical misalignment and go to the relevant specialist as soon as possible. Especially for the elderly, if they do not pay attention to it, it is likely that the cervical misalignment will lead to prolonged cerebral ischemia and hypoxia, and even the risk of cerebral thrombosis. However, it should be noted that middle-aged and elderly patients with vertigo are often diagnosed with cervical spine growth and given traction treatment, but the dizziness worsens instead. This is often due to misdiagnosis, because hyperplasia does not cause dizziness and neck pain, but cervical vertigo is mainly caused by misalignment of the first two cervical vertebrae, which cannot be seen by simply looking at the frontal and lateral cervical spine X-ray films. If there is protrusion and pressure pain in the cervical spine, the misalignment can be confirmed. The problem of cervical spine misalignment is becoming more and more common and is related to the development of sleeping habits. As the neck muscles relax during sleep, the protection of the cervical spine is poor, and if you often sleep on your stomach or twist, it is easy to cause cervical joint misalignment. Many children of three or five years old have this problem, often to the computer white-collar workers in a short lunch break often develop a bad sleeping posture, and doze off in the car is also prone to cause cervical dislocation. So the sleeping position must be paid attention to, the height of the pillow should be based on the position to determine, used to supine can choose a lower pillow, used to side lying can choose a higher pillow. If you feel often sleepy, groggy and inattentive, it may be a precursor of cervical misalignment.
