Symptoms and Causes of Migraine Headache

Migraines can be a real problem especially when you are working 9 to 5 and you just can''t afford to be unproductive at work. There is however nothing you can do as headaches like these can be so severe that it can affect your concentration and your mood. Migraine headaches are recurrent headaches that occur on one side of the head.

Compared to the usual type of headache, the tension headache, which often occur on the entire head area, the pain in migraine headaches is more localized and much more specialized. It is however harder to predict when it will occur as migraine headaches do not present any warning signs. In fact, these types of headache will just happen when you least expect it to.

There are however kinds of migraines where some symptoms may be observed. One type is what is commonly called as the classic migraine headache where in the person suffering from it may see a hallucination called ''aura'' before it actually occurs. Auras are visual hallucinations that resemble lights or zigzagging lines in the person''s line of vision. The hallucination can last from about 15 minutes up to an hour. The duration vary from one case to another. There may also be pain in the areas surrounding the eyes, temporary blind spots and blurred vision.

Still, it does not happen out of the blue. Although the underlying causes of migraine headaches is still up for debate, there are predisposing factors that can trigger its attack. Migraine headaches are basically caused by the inflammation or constriction of the blood vessels in the head. The changes in the size of the vessels may be due to some medical conditions such as lesions and inflammations caused by infections. If the migraine headaches become severe and frequent, it is important that you go to your doctor and seek medical help.

Environmental and other physiological factors may also contribute in the occurrence of migraine headaches. One factor is stress-related. Over exertion and over fatigue especially in the eye area can cause severe migraine. Depression and anxiety are also factors that you should look into.

Other medical conditions that can start a migraine attack are colds, cough, influenza, and sinusitis. Food and diet may also play a role. Some experts believe that eating chocolates, drinking coffee and abusing alcoholic drinks may contribute in the attack. Sensorial triggers such as over bright lights, too much noise and strong odors may also trigger an attack.
