What causes a throbbing headache?

Answer:
A headache is caused by the swelling of blood veins/vessels in the head, obviously. This excessive swelling causes pressure on the brain since the swelling is above normal. In turn, the more dilated your blood vessels are, the more pressure there is inside your head. Which causes the headache.

Now, everyone is familiar with the drug caffeine. Caffeine is actually very effective in releaving headache pain. This is because the dilated veins are constricted back to a normal size by the caffeine, in turn decreasing the effects of the headache.

Hope this helps..
