The common causes of headache and dizziness are as follows: First, cerebrovascular diseases. For example, cerebral arteriosclerosis, cerebral thrombosis, cerebral embolism, and insufficient blood supply of cerebral arteries can be identified by head CT or MRI. Second, cervical spondylosis. When the cervical intervertebral disc protrudes and compresses the nerves and blood vessels, it will also cause headache and dizziness. The most important thing in this situation is to expand the blood vessels of the vertebral basilar artery, and can also be treated by physical therapy of traditional Chinese medicine, such as traction and silver needles. Third, hypertension can also occur. Therefore, it is better to go to the hospital in time for frequent and repeated dizziness and headache.
