Straightening of the cervical spine curvature may have the following consequences: First, insufficient blood supply to the brain: due to straightening of the cervical spine curvature, the blood supply to the vertebral artery will be insufficient, and brain tissue will suffer from ischemia and hypoxia. This causes severe headache, dizziness, nausea, vomiting, chest tightness and panic, and memory will also be significantly impaired. Second, nerve compression symptoms: cervical spine curvature straightening easily compresses cervical spinal cord nerves, including nerve roots, and patients will have serious clinical symptoms such as weakness of the limbs, radiating pain in the upper limbs and muscle atrophy of the limbs. Patients who develop cervical curvature straightening must be treated as soon as possible. Choose conservative treatment or surgical treatment according to the severity to restore the cervical spine physiological curvature as soon as possible to alleviate the above serious adverse consequences and avoid serious consequences such as brain atrophy, limb weakness or tetraplegia.
