After recovering from a cold, you should have a magnetic resonance imaging (MRI) of the head, cervical spine and cervical vascular ultrasound to rule out dizziness caused by cerebrovascular lesions or dizziness caused by cervical spine lesions. If there are no obvious abnormalities in the above examinations, dizziness is often secondary to the recovery from a cold. After a cold, there will be nasal congestion and edema, which will affect the ventilation of the nasal cavity and easily lead to hypoxia. Active treatment of cold can effectively relieve the phenomenon of dizziness, using cold medications, such as Senso-Kang, Aminogalactam capsule and Vitamin C Yin Qiao tablets for adults; for children, you can use Pediatric Aminogalactam Dispersible Tablets, Aminogalactam Granules and Pediatric Cold and Fever Granules.
