A confusing situation. A hard exam. A long, tedious talk. In situations like these, a person may normally feel like having a headache. But unfortunately, some people experience more than just a simple headache. Throbbing on an area in your head may be a sign of migraine. But what is migraine and how is it different from a headache?

A headache is described as the pain in the head located above the eyes and the ears, behind the head, or at the back of the upper neck. Migraine, on the other hand, refers to a much more painful headache. References with regards to migraine include the throbbing of one or both areas in the head (bilateral), sensitivity to light (photophobia), sounds (phonophobia), and smell, nausea, vomiting, sleep disruption, and even depression. Having these symptoms may lead into concluding that the person is experiencing migraine without aura, or common migraines. Having a migraine attack like this can make the person feel more tired and weak once the migraine has passed. The person's hand and feet may feel sweaty and cold, and sometimes there is the presence of a different intolerable odor. This is associated also with pain that interferes or becomes worse as the person goes through his daily activities. Other people occasionally experience the sight of flashing lights, wavy images, hallucinations, zigzag lines, or getting double vision, if not temporarily blind. This migraine episode is characterized as migraine with aura. Also called classic migraines, this would begin for about fifteen to thirty minutes before getting the headache itself.

Causes of migraines may include functional changes in the nervous system (trigeminal), which is a substantial pain road in your nervous system. C0hemical imbalances in the person's brain (including seratonin) that plays an important role for pain messages going through this specific pathway is also another cause of migraine. If experiencing a headache, the person's seratonin level will drop. In line with this, the trigeminal nerve releases a substance called neuropeptides, that travels to the brain's outer covering (meninges). This in turn will cause the blood vessels to be inflamed and dilated.
