There is a difference between dizziness and headache, but the two symptoms often appear together in clinical practice. Dizziness refers to the patient’s feeling of being light-headed, feeling that the body is floating or walking floating. It may be caused by physiological factors, such as mental stress, fatigue, lack of sleep, or extreme brain fatigue, or by hypotension, hypoglycemia, cerebral arteriosclerosis, or cardiogenic cerebral blood supply deficiency. Headache is relatively common in clinical practice, and various causes of stimulation of pain-sensitive structures in the patient’s brain can lead to headache symptoms. For example, migraine, neuropathic headache, and myotonic headache during cold and fever can cause patients to have headache symptoms.
