The most common site of headache in patients with blood pressure is located in the occipital region at the back of the head, but it can also be located bilaterally or unilaterally in the temple area. Some patients show pain in the forehead or orbital region, and some patients show swelling and throbbing pain in the whole head. Hypertensive headache is caused by high blood pressure causing cerebral vascular spasm and insufficient blood supply to the brain leading to ischemia and hypoxia in brain tissue. In some patients, a sharp increase in blood pressure causes an increase in vascular permeability, which leads to cerebral edema, causing an increase in intracranial pressure and headache. Patients with hypertension should actively control their blood pressure to prevent unstable and rapid increases in blood pressure, which can seriously lead to cerebral hemorrhage or acute cerebral infarction.
