Cervical disc herniation can cause dizziness due to compression of sympathetic nerves, vertebral artery or spinal cord, but not every patient with cervical disc herniation will be dizzy. Cervical intervertebral discs are subjected to external forces and other factors on the basis of degeneration, which can lead to disc herniation, compression and irritation of spinal nerves and vertebral arteries. If the sympathetic nerve is stimulated and the vertebral artery is compressed, headache, dizziness, tinnitus, tardive dyskinesia and other symptoms can occur. If the nerve root is compressed, symptoms such as shoulder and neck pain, numbness of the hands, and decreased muscle strength of the upper limbs may occur. If the spinal cord is compressed, symptoms such as limb movement disorders, the feeling of feet stepping on cotton, and even urinary and fecal dysfunction may occur. If cervical disc herniation causes dizziness, early standardized treatment is recommended to reduce the adverse effects of the disease.
