Headaches in any form are always very painful to the sufferer. However, some headaches, such as migraines, for example, can create even more problems than just a headache. These problems could be nausea, light sensitivity and a banging pain in the head. Sometimes the headache is felt on one side of the head, although at other times you can feel the pain on both sides of your head at the same time.

The actual causes of migraine headaches has not been found as of yet, although there are some theories as to why we experience migraine headaches. The most common theory is that a change in the blood flow within the brain is one of the trigger causes of migraine headaches. Another theory about migraine headache is that it could be caused by pain sensing nerve chemicals called neuropeptides.

Many medical professionals speculate that neuropeptides relax the smooth muscle that surrounds the cranial blood vessels. This relaxation causes the blood vessels to dilate. This blood vessel relaxation increases the flow of blood and other cranial fluid to the brain. This increase in fluids is thought to be the cause of migraine headaches.

These cranial fluids cause inflammation, pain, sensitivity, tissue and blood vessel inflammation during the time of migraine headaches. Some people think that the aura that is sometimes seen during a migraine headache is caused by the constriction of blood vessels that became dilated during the beginning phase of the migraine headache.

Another theory as to the causes of migraine headaches has been linked to genetics and inheritance. These theories state that a child of migraine sufferers will have a 50% probability of getting migraine headaches too.

The chances of inheriting migraine headaches become even greater if both parents are known to suffer from this painful type of headache. Should both parents be known to have frequent migraine headaches the chances of the child inheriting migraine headache symptoms is about 70%.

Now even though many professionals think that inheritance plays a large role in migraine headaches the genes that may be considered as the causes of migraine headaches have not been identified or even isolated. When we begin to experience migraine headaches the only warning signs that we may receive are a throbbing pain in the temple area and slight nausea.

As the symptoms of the migraine progresses, the pain becomes much more severe. Unfortunately, since the causes of migraine headaches have yet to be found and we dont know what triggers these attacks, there are no medications to cure this kind of headaches yet.
