Cervical spondylosis causes dizziness for the following reasons: First, cervical spondylosis itself disc herniation hyperplasia, compression of the spinal cord and nerve root stimulation caused by cervical pain, which causes cervical stiffness, poor blood supply caused by dizziness. Secondly, the proliferation caused by cervical spondylosis stimulates the local nerves, which causes plant nerve dysfunction. The stimulation of nerves can also aggravate dizziness, and at the same time, if the hyperplasia is very serious, it really affects the blood vessels in the head, resulting in insufficient blood supply and ischemia of the posterior circulation, etc., which can also cause dizziness. Even if there is no obvious pressure, the bone and inflammatory substances stimulate the nerves into the blood vessels inside the skull, which can also result in spasm and contraction of blood vessels, and although there is no pressure, it can also result in ischemia and insufficient blood supply and cause dizziness. If the dizziness persists and the sky rotates, nausea, it is related to the rapid head movement, also need to exclude the neurology and ENT disease, need to be examined clearly and symptomatic treatment.
