In most cases of dizziness caused by cervical spondylosis, the symptoms may worsen as the patient moves around, and the condition will be alleviated after lying down and resting. Most of the dizziness caused by cervical spondylosis is due to the compression of the vertebral artery by the cervical vertebral growths and prolapsed discs, resulting in the narrowing of the vertebral artery and causing dizziness due to insufficient blood supply to the brain. In addition to this, some patients also have a series of symptoms such as numbness of fingers, weakness of limbs, nausea, blurred vision and tachycardia. After lying down and resting, the patient’s blood supply to the brain can be restored, so the symptoms of dizziness and nausea will be relieved to a considerable extent. If the relief is not obvious in some patients, some oral medications or injections for blood vessel expansion can be added, and the symptoms can be gradually relieved after 3-5 days.
