Migraine
A
migraine is a severe form of recurring headache.
The pain is generally concentrated on one side of
the head.
Although
much about headaches still isn't understood, a key
cause of a migraine is changes to the blood flow
within the brain.
Blood
vessels of the brain supply it with oxygen and
nutrients.
Nerves,
which are sensitive to pain, terminate in these
vessels.
Certain
triggers dilation and constrict these vessels.
The
repeated dilation and constriction causes the
nerve walls to stretch resulting in the discomfort
of a migraine.

that can cause a migraine
1.Stress
and anger

smells, fumes, tobacco smoke, light glare, weather
changes.
3.Monthly
periods, birth control pills, estrogen therapy.

much, too little or interrupted sleep.
5.Hunger,
fasting, specific foods or beverages.
6.Certain
