Symptoms Headache

Migraine headaches often begin in childhood, adolescence or early adulthood. Migraines may progress through four stages — prodrome, aura, attack and postdrome — though you may not experience all the stages.

Prodrome
One or two days before a migraine, you may notice subtle changes that may signify an oncoming migraine, including:
Constipation
Depression
Diarrhea
Food cravings
Hyperactivity
Irritability
Neck stiffness
Aura
Most people experience migraine headaches without aura. Auras are usually visual but can also be sensory, motor or verbal disturbances. Each of these symptoms typically begins gradually, builds up over several minutes, then commonly lasts for 10 to 30 minutes. Examples of aura include:
Visual phenomena, such as seeing various shapes, bright spots or flashes of light
Vision loss
Pins and needles sensations in an arm or leg
Speech or language problems
Less commonly, an aura may be associated with aphasia or limb weakness (hemiplegic migraine).
Attack
When untreated, a migraine typically lasts from four to 72 hours, but the frequency with which headaches occur varies from person to person. You may have migraines several times a month or much less frequently. During a migraine, you may experience some of the following symptoms:
Pain on one side of your head
Pain that has a pulsating, throbbing quality
Sensitivity to light, sounds and sometimes smells
Nausea and vomiting
Blurred vision
Diarrhea
Lightheadedness, sometimes followed by fainting
Postdrome
The final phase — known as postdrome — occurs after a migraine attack, when you may feel drained and washed out, though some people report feeling mildly euphoric.
When to see a doctor
Migraine headaches are often undiagnosed and untreated. If you regularly experience signs and symptoms of migraine attacks, keep a record of your attacks and how you treated them. Then make an appointment with your doctor to discuss your headaches and decide on a treatment plan.
Even if you have a history of headaches, see your doctor if the pattern changes or your headaches suddenly feel different.
See your doctor immediately or go to the emergency room if you have any of the following signs and symptoms, which may indicate other, more serious medical problems:
An abrupt, severe headache like a thunderclap
Headache with fever, stiff neck, rash, mental confusion, seizures, double vision, weakness, numbness or trouble speaking
Headache after a head injury, especially if the headache gets worse
A chronic headache that is worse after coughing, exertion, straining or a sudden movement
New headache pain if you're older than 50

What Is A Migraine

A migraine headache is a form of vascular headache. Migraine headache is caused by vasodilatation (enlargement of blood vessels) that causes the release of chemicals from nerve fibers that coil around the large arteries of the brain. Enlargement of these blood vessels stretches the nerves that coil around them and causes the nerves to release chemicals. The chemicals cause inflammation, pain, and further enlargement of the artery. The increasing enlargement of the arteries magnifies the pain.

Migraine attacks commonly activate the sympathetic nervous system in the body. The sympathetic nervous system is often thought of as the part of the nervous system that controls primitive responses to stress and pain, the so-called "fight or flight" response, and this activation causes many of the symptoms associated with migraine attacks; for example, the increased sympathetic nervous activity in the intestine causes nausea, vomiting, and diarrhea.
Sympathetic activity also delays emptying of the stomach into the small intestine and thereby prevents oral medications from entering the intestine and being absorbed.
The impaired absorption of oral medications is a common reason for the ineffectiveness of medications taken to treat migraine headaches.
The increased sympathetic activity also decreases the circulation of blood, and this leads to pallor of the skin as well as cold hands and feet.
The increased sympathetic activity also contributes to the sensitivity to light and sound sensitivity as well as blurred vision.
Migraine afflicts 28 million Americans, with females suffering more frequently (17%) than males (6%). Missed work and lost productivity from migraine create a significant public burden. Nevertheless, migraine still remains largely underdiagnosed and undertreated. Less than half of individuals with migraine are diagnosed by their doctors.

Symptoms If Migraine

Vision disturbances, or aura, are considered a "warning sign" that a migraine is coming. The aura occurs in both eyes and may involve any or all of the following: * A temporary blind spot * Blurred vision * Eye pain * Seeing stars or zigzag lines * Tunnel vision Not every person with migraines has an aura. Those who do usually develop one about 10 - 15 minutes before the headache. However, it may occur just a few minutes to 24 hours beforehand. Migraine headaches can be dull or severe. The pain may be felt behind the eye or in the back of the head and neck. For many patients, the headaches start on the same side each time. The headaches usually: * Feel throbbing, pounding, or pulsating * Are worse on one side of the head * Start as a dull ache and get worse within minutes to hours * Last 6 to 48 hours Other symptoms that may occur with the headache include: * Chills * Increased urination * Fatigue * Loss of appetite * Nausea and vomiting * Numbness, tingling, or weakness * Problems concentrating, trouble finding words * Sensitivity to light or sound * Sweating Symptoms that may linger even after the migraine has gone away include: * Feeling mentally dull, like your thinking is not clear or sharp * Increased need for sleep * Neck pain

Causes Migraine Headaches

A migraine is a severe headache that is recurring. You may experience migraines monthly or once or twice a year. Migraines can be accompanied by extreme sensitivity to lights and sounds, nausea and vomiting. A severe migraine will be disabling to most people. Migraines have long been a sort of medical mystery. Researchers are not sure of the exact cause of migraines, but over the years have constructed a few theories. This article is going to look at the possible causes of migraine headaches.
A lot of researchers think that migraines are caused by an imbalance in the complex systems of nerves in the brain and neurotransmitters. Neurotransmitters are chemicals in the brain responsible for pain perception and emotions.
Serotonin is one of the neurotransmitters that researchers have studied. It has been proven that when you have a headache, your levels of serotonin drops. This in turn will cause the trigeminal nerve in your brain to release neuro peptides. These chemicals will cause the blood vessels on the outside covering of your brain to swell and the resulting pressure will produce a headache. This is the assumed mechanism of how a headache develops, but what causes this to happen.
Your headaches may be the result of certain triggers. The triggers that can produce a migraine are:

• - Certain foods can trigger a migraine in a lot of people. Common food triggers are alcohol, chocolate, caffeine, aged cheeses, monosodium glutamate and other canned or processed foods.
• - Sometimes skipping a meal can bring on a migraine also.
• - Intense physical activity, including sex, can trigger a migraine. Too much sleep or too little sleep can also be a trigger.
• - Stress is a big factor in triggering migraines. If you have worked hard all week and are starting to relax on the weekend, it may be ruined by a weekend migraine headache.
• - Any type of change in your environment such as, the weather, temperature, barometric pressure and even a change in the time zone, can trigger a migraine.
• - Some people are overly sensitive to all types of sensory stimulus such as, bright lights and certain smells. Certain perfumes or flowers have been known to trigger migraine pain.
• - Women who are going through hormonal changes will be more at risk for developing a migraine. Researchers aren't sure why the fluctuations of hormones will trigger a migraine, but the incidences of migraines seem to increase right before or during a woman's period.
• - Certain medications have been know to trigger migraine headaches.

If you are having frequent migraine headaches, try to pinpoint the trigger for them. Try keeping a journal of everything that you eat or do that's out of the ordinary each day. When you have a migraine read back through your journal and try to identify a possible trigger. If you haven't started treatment for migraines, see your doctor. He can prescribe medicine that will decrease the migraines or make them less intense. Don't suffer in pain anymore, find the cause of your migraine headaches.
