Causes and nature of headaches.

4. Low or high blood pressure. I want to note right away that a headache does not always mean a change in blood pressure. Very often, patients only find out they are living with high blood pressure when they visit a doctor. A drop in blood pressure "hypotonics" can feel like a general weakness, loss of strength, drowsiness. However, vasospasm with a drop in pressure or their expansion with an increase in pressure can lead to a headache, since any vessel is entwined with a nerve. Headache with a decrease in blood pressure is felt as squeezing in the temples, in the eyes, in the forehead, accompanied by cold hands and feet and a desire to sleep. With an increase in blood pressure, it is a sharp, throbbing pain.
