Best answer:

Answer by Dustin M
Because a migraine headache is actually a physical spasm of the brain. Sometimes the spasm affects the part of the brain that controls eye-sight, causing you to lose it until the spasm is over.

    Actually, contrary to the other answers, the brain has no nerves and can sense no pain. What you feel is the slight swelling (dilating-as opposed to constricting) blood vessels hitting the very sensitive nerves surrounding your brain, which can feel the slightest bit of pressure and respond with pain. Some of these vessels are around your optic (eye) nerves which affect your sight and causes the aura or other visual disturbances. Caffiene is a natural way of constricting the blood vessels back if you don’t have migraines severely or very often. A couple sodas or an excedrine will do the trick rather than just treating the pain with a pain pill.

    If this is new to you, I suggest you see your GP or a neurologist to confirm what you are experiencing is a migraine and not a TSA (mini stroke) or other more serious issue.
