Nerve block therapy generally works for sympathetic cervical spondylosis. Tissue lesions in the cervical nerve roots, posterior longitudinal ligaments, small joints and vertebral arteries, dura mater and other tissues can reflexively stimulate the sympathetic nerves, resulting in a series of clinical signs, which is called sympathetic cervical spondylosis. Treatment modalities include cervical brace protection and functional exercises, traction, and medication. Nerve block treatment is to reduce the stimulation and compression of nerve roots, spinal cord, vertebral artery, and sympathetic nerves through the combination of drug injections, and to reduce the acute inflammation of spinal nerves and their surrounding tissues such as edema and exudation, so as to achieve the effect of treating sympathetic cervical spondylosis. If the diagnosis of sympathetic cervical spondylosis is confirmed, it is recommended to go to the hospital in time and carry out standardized treatment under the guidance of doctors in order to reduce the adverse effects.
