Cervical curvature can be corrected by changing postural habits, traction therapy and surgery. 1. Changing postural habits: In case of straightening of cervical curvature, it is necessary to avoid prolonged bowing of the head, move the neck appropriately, and do not put on too high a pillow, which will help the gradual recovery of cervical curvature. 2. Traction therapy: pulling the cervical vertebrae through external force can stretch the intervertebral space, and the cervical curvature can be restored after appropriate traction therapy. 3. Surgery: If the cervical spine tissue is sclerotic, hyperplasia and other chronic inflammatory changes, surgery can also be used to repair the local lesions and reshape the physiological curvature of the cervical spine. Straightening of the cervical curvature may cause dizziness, fatigue and other uncomfortable symptoms, it is necessary to consult a doctor and receive regular treatment in order to slowly restore the cervical curvature, which will help the health of the cervical spine.
