Migraine is a severe form of headache wherein, the excruciating pain is accompanied by an extreme sensitivity to sound and light; you also experience nausea. The headaches usually affect either side of the head and are throbbing in nature. Hot flashes, numbness of limbs and blind spots in the eye; these are often considered as warnings. In certain cases, migraines can cause blackouts that can range from a few seconds to a few minutes.
Migraine occurs in four stages:
But the occurrence of these stages varies across individuals. The causes of migraines aren’t specifically understood. It may be due to the interaction of the brain stem with the trigeminal nerve, which is an important pain pathway of the brain. Imbalances in hormonal levels or in the levels of neurotransmitters such as serotonin may also prove to be a causal factor.
Migraine may be triggered due to stress, physical exertion, and excess intake of alcohol or food additives such as MSG (Monosodium Glutamate). Changes in the environment and sleeping patterns may also be probable culprits.
Migraine can be easily distinguished from regular headaches, given the fact that migraines last longer and are rather severe in nature with pain felt in one part of the head. Most people experience the ‘Aura’stage where they have visual flashes right before headache. Nausea, eye pain or sensitivity to light and sound are other factors helpful in distinguishing migraine from other headaches.
Symptoms can occur a while before headache, immediately before headache, during headache and after headache. Although not all migraines are the same.
