Characteristics of a Migraine

Many scientists now believe that serotonin is the main culprit in the chemical reactions that occur during a migraine. Serotonin is a chemical in your brain that can constrict blood vessels and stimulate pain receptors. Levels of serotonin are unusually high just before a migraine and unusually low during the migraine attack.

Attacks can occur any time, day or night, though they often occur first thing in the morning. Routine activity, exercise, or slight head movement makes the pain worse. Some patients report that the simple act of trying to lift their heads off the pillow results in excruciating pain. Symptoms may appear up to several hours before the headache, or the pain may strike without any warning. Some people feel irritable during migraine attacks and seek solitude, often in a darkened room. Following an attack, many people feel washed out and listless.

Signs of an impending attack

When a migraine is on its way, some people say they can feel it coming. It's like their bodies have a built-in warning system. Getting to know these warning signs can help you take action at the best time — before the pain begins.

The signs can be subtle. You might have a change in mood — either up or down — or not feel like eating. You might feel washed out and tired. You might even feel dizzy or numb. Either way, if you notice any changes that seem out of the ordinary, there's a chance that a migraine may soon follow.

As the pain gets closer, your body may also send visual warning signs. You might see flashing lights, bright zigzagging lines, or a blind spot. Experts call this special type of headache "migraine with aura."
