Headaches are pain which often occur in the nerves, blood vessels and muscles of the head and neck. However, a headache does not occur because the brain hurts as the brain itself could not sense pain. Instead, headaches can occur due to various reasons which doctors usually classify under primary and secondary. Primary headaches happen but has nothing got to do with the medical condition of a person. Contrastingly, secondary headaches are associated with medical conditions like sinus.
The three types of primary headaches are migraine headaches, tension headaches and cluster headaches.
Migraine headaches may be caused by reduced blood flow to various areas of the cerebral cortex. A person with migraine headache may be sensitive to light and noise, feel nauseous or even experience intense pain on one side of the head.
Tension headaches may be caused by muscle strains in the head and neck or even emotional stress. This kind of headaches causes aching pains on both sides of the head but may lead to intense pain too. Factors like poor eyesight may cause tension headaches.
Cluster headaches are headaches that does not occur only once but occurs many times over weeks or even months. This kind of headache usually happen on one side of the head, around the eye.The cause of cluster headaches are currently unknown.
In contrast, secondary headaches occur due to some issues of the body, for example, flue and these headaches usually go away when the disease is cured.
Reflections:
I did the topic on "Headaches" as I find it very interesting and I am curious to find out why humans get headache out of nowhere. This research shows the different kind of headaches and the cause of the headaches, thus opening up another point of view for me on this topic of "Headaches". Headaches have often brought to human much disturbance and may even make a person feel frustrated easily when down with a headache. Hopefully, this post can analyse the different kinds and causes of headaches!
