Frequent headaches and dizziness may be due to neuritis caused by a cold or fever, or cervical spondylosis can cause similar symptoms, and intracranial hematomas can also cause abnormal sensations in the head. After a cold or fever, the body’s inflammatory response is intense, and viruses or bacteria will continue to spread throughout the body with the blood flow, causing dizziness and headaches. Degenerative lesions of the cervical spine after cervical spondylosis or herniated intervertebral discs can compress the vertebral artery blood vessels, thus causing insufficient blood supply to the brain, resulting in slow ischemia and hypoxia in the brain, which can cause nerve disorders, resulting in local dizziness and headache. The presence of intracranial hematoma, especially after an external injury, can lead to local thrombosis and increased local pressure, which can cause abnormal sensations in the head. Hypertension, diabetes, can also cause dizziness and headache.
