Headaches in any form are always very painful to the sufferer. However, some headaches, like migraines, for example, can create even more problems than just a headache. These problems could be sickness, light sensitivity and a throbbing 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 real causes of migraine headaches has not yet been discovered, although there are a few theories why people have migraine headaches. The most common theory is that a change in the blood flow within the brain is one of the triggers that causes migraine headaches. Another theory about migraine headache is that it could possibly be caused by pain sensing chemicals called neuropeptides.

Many medical professionals think that neuropeptides relax the muscle that surrounds the cranial blood vessels. This relaxation makes the blood vessels dilate. Then those relaxed blood vessels increase 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 swelling 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 about the reason for migraine headaches has been associated with the genetics of inheritance. These theories state that a child of migraine sufferers will have a 50% chance of having migraine headaches too.

The probability of inheriting migraine headaches is even greater if both parents are sufferers of this painful sort of headache. If both parents are known to have frequent migraine headaches the chances of the child having migraine headache symptoms is about 70%.

However, even though some professionals think that genetics plays a part in migraine headaches, the genes that are considered to be 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 expect to receive are a throbbing pain in the temple area and slight sickness.

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