Recently, findings at Massachusetts General Hospital has revealed that the cortex, which is the intricate part of the brain that helps in processing sensations, is around 21 percent thicker than in the normal human being. Although, the cause of migraine is still not known but patients who are suffering from this syndrome are also prone to back ache and allodynia.
Migraine headaches usually occurs when serotinin, a brain chemical, which when released into the blood, leads to further chemical and blood vessel changes in the brain. Nausea, vomiting, fatigue, depression, lethargy, photosensitivity, aura, visual disturbances, and sometimes sensitivity to smell are some of the known symptoms of this disorder. Migraine headaches are itself very intense and even a slight movement can worsen the situation.

Migraine headache is caused by a combination of vasodilatation (enlargement of blood vessels) and the release of chemicals from nerve fibers that coil around the blood vessels. During a migraine attack, the temporal artery enlarges. (The temporal artery is an artery that lies on the outside of the skull just under the skin of the temple.) Enlargement of the temporal artery stretches the nerves that coil around the artery and causes the nerves to release chemicals. The chemicals cause inflammation, pain, and further enlargement of the artery. The increasing enlargement of the artery magnifies the pain. A migraine headache is a form of vascular headache.
