The experiences are also different between different people. Migraine headaches are very common and can last from a few hours to three days.  Unfortunately, these headaches are one of the least understood and poorly treated medical disorders, since they are likely to result from a complex interplay of genetic, environmental, and neurological factors that vary from person to person.

Alongside the common symptoms such as throbbing, searing pain, which may or may not be one-sided, some patients also experience “auras” prior to onset, while some of them do not. According to research, over 300 million people across the world (that’s 6-7 percent men and 15-18 percent women) have migraine headaches. Around 20 million migraine attacks take place every day.

Causes Of Migraine
 The causes of migraines have been examined in a great number of studies, but none of them can fully explain the occurrence of migraines in all sufferers. Sometimes these theories can be conflicting, but the majority of them asserts that the causes of a migraine include:

Excess flow of blood in the brain. There are studies that show that such headaches don’t follow construction and reduction in blood flow, but only an increase by almost 300 percent. But after the migraine attack occurs, the blood circulation seems normal or even falls slightly.

A neurological disorder associated with the function of a nerve cell. It is believed that migraines occur because of a neurological disorder associated with nerve cell activity which spreads across the brain and thus causes pain.

Vascular constriction within the brain. It is believed that migraines may also occur due to initial constriction in a blood vessel and reduction in blood flow, and then the blood vessels dilate and stretch. This causes activation of neurons that signify pain.

Alterations in serotonin (a brain chemical). It is believed hat migraine pain may be caused by inflamed and swollen blood vessels in our brain when the levels fall.

Vitamin deficiency and migraines

According to the latest study, it was discovered that vitamin B6, B12, and folic acid supplements cause a two-fold reduction in migraines over a six-month period. This was also suggested by previous research, such as a 2004 study in the European Journal of Neurology, which pointed out that migraine attacks can be avoided by consumption of high doses of B2 (riboflavin).

Moreover, levels of homocysteine production can be increased by some gene mutations and dysfunctions, which can make you more prone to migraine attacks. It was discovered that vitamins B6 and B12 reduce homocysteine levels. In addition, researchers found that depending on your genotype, one may need a higher or lower dose in order for it to work.
