Migraine is a disabling headache and the symptoms are very severe. Up to 18% of women and 10% of men suffer from migraine headache. Since a lot of people would not be able to tell apart a normal headache from a migraine, the actual numbers can be much higher. It would be useful to know the impact of a migraine headache, know its symptoms and hence be better prepared when it strikes. Usually migraine causes episodes of severe or moderate headache (which is sometimes one-sided and pulsating) lasting from several hours to three days. It can also be accompanied by gastrointestinal upsets, such as nausea and vomiting, and a heightened sensitivity to bright lights (photophobia) and noise.

Migraine headaches are one of those things for which researches still are not able to find the exact cause. Some believe that the sudden swelling of blood vessels in the brain causes migraine headaches. Meanwhile others claim it’s due to a constricting of those very same blood vessels. Either way they agree that these headaches have something to do with a chemical interaction that affects the blood flow to the brain.

The severity of these headaches does vary but overall, migraine sufferers find the pain very intense. They will usually find themselves a dark quiet room to rest in since shutting out all sights and sounds around them helps to get through the migraine episode. People will recover from a migraine attack within anywhere from a few minutes to a few hours while others will have the headache linger for days. Some have background headaches the day after suffering a migraine. They do not usually get any worse than that and then they fade away. Migraine headaches are known as episodic headaches, as the sufferer feels normal between headache events.

Some people experience unusual symptoms before the onset of migraine headache. It should be immediately read as a symptom and preparation should be made for handling the headache. They see something visual, known as an aura, off to the side, usually the side of the head that they have their migraine pain. For some its lights flashing that they see while for others it is vague shapes. There are still other migraine sufferers who lose vision at the side. This loss can also move around somewhat getting bigger as it goes. Once the headache is ready to come on all these types of visual incongruities disappear. This is common among ocular migraine sufferers.
