Migraines is one of the most common disorders of the nervous system that can cause regular headaches and other related problems such as tingling, numbness or weakness on one side of the body. Although, the initial indication of the migraine is the incidence of aura such as visual disturbance like bright spots or crisscross lines looking before the eyes.

Aura begins with temporary contraction of the blood vessels supplying blood to the central nervous system. As soon as these blood vessels, tightly restricted till then, open up and a gush of blood flows through to the central nervous system, an unadorned headache, mostly one-sided, follows.
