What is angioneurotic headache?

Neurovascular headache is caused by vasoconstriction and diastolic dysfunction, such as vascular neuropathic pain caused by nerve dysfunction, if the face is affected, vascular compression trigeminal nerve, through nerve impulse to the cerebral cortex, causing vascular neuropathic headache. Other common causes of headache in clinical practice include traction of intracranial arteries, veins and nerves, or stimulation of meninges, such as muscle tension, nerve pricking and traction. In addition, headache can also be caused by abnormal chemical transmitters in the brain.
