Migraine: This disease is usually caused by long-term work and rest disorders, mental stress and other reasons.

Hypertension: When blood pressure fluctuates and rises, especially when it rises by a large margin, the pressure inside the cerebral blood vessels increases excessively, which constantly produces a strong stimulation of the meninges, and may cause a sharp pain in the head, which may be accompanied by dizziness, nausea and other symptoms. The pain in the head may also be related to other factors, if the symptoms can not be effectively relieved, it is recommended to consult a doctor as soon as possible to confirm the diagnosis, and then give targeted treatment.
