Cervical spondylosis is mainly caused by cervical disc degeneration and cervical spine osteophytes, which produce certain compression on cervical nerve roots and spinal cord. Clinically, there are generally no 10 major symptoms of early cervical spondylosis, and depending on the location early patients may have the following manifestations: 1. neck: if patients have stiff neck, restricted movement, or sound when turning the neck, it may be one of the early symptoms of cervical spondylosis, and may also lead to surrounding 2. Back: In addition to neck pain, patients with cervical spondylosis may have painful symptoms radiating to the back of the shoulder because the neck muscles are connected to the back of the shoulder; 3. Upper limbs: Neurogenic cervical spondylosis may compress the nerve roots in the neck, resulting in symptoms such as pain in the upper limbs and numbness in the hands; 4. 5.Brain: If patients suffer from cervical spondylosis, it can cause insufficient blood supply to the brain, so early symptoms such as headache and dizziness may also appear, which are common in vertebral artery cervical spondylosis; 6.Eye: Cervical spondylosis can cause spasm of the basilar artery, which can cause ischemia of the occipital lobe of the brain, resulting in symptoms such as blurred vision, hallucinations, diplopia, and even transient blindness; 7.Ear: Because cervical spondylosis can lead to insufficient blood supply to the brain, and can have a negative impact on the nerves. 8. Cardiovascular: If the patient suffers from vertebral artery cervical spondylosis, sudden collapse may occur due to insufficient blood supply to the brain and abnormal blood pressure; 9. Vomiting and other symptoms; 10, mental: early cervical spondylosis patients may also appear insomnia, dreamy and other symptoms.
