Cervical spondylosis can cause tinnitus. Cervical spondylosis is caused by hyperplasia, stiffness, adhesions and inflammatory substances that irritate the muscles of the neck, leading to irritation of blood vessels, especially those entering the head, or direct compression after hyperplasia. Irritation of the nerves of the blood vessels after hyperplasia can cause vasospasm, or even insufficient blood supply after direct compression. Insufficient blood supply affects the blood supply to the brain and the skull, causing tinnitus. Cervical spondylosis can also stimulate the sympathetic nerve endings around the cervical spine, causing some symptoms of sympathetic nerves. Typically, tinnitus is accompanied by dizziness, headache, facial numbness, and blurred vision. Patients with cervical spondylosis causing tinnitus should go to the hospital in a timely manner, ask the doctor for a clear diagnosis and symptomatic treatment.
