A migraine can cause severe throbbing pain or a pulsing sensation, usually on one side of the head. It's often accompanied by nausea, vomiting, and extreme sensitivity to light and sound. Migraine attacks can last for hours to days, and the pain can be so severe that it interferes with your daily activities.
For some people, a warning symptom known as an aura occurs before or with the headache. An aura can include visual disturbances, such as flashes of light or blind spots, or other disturbances, such as tingling on one side of the face or in an arm or leg and difficulty speaking.
Medications can help prevent some migraines and make them less painful. The right medicines, combined with self-help remedies and lifestyle changes, might help.
Migraines, which often begin in childhood, adolescence or early adulthood, can progress through four stages: prodrome, aura, attack and post-drome. Not everyone who has migraines goes through all stages.
One or two days before a migraine, you might notice subtle changes that warn of an upcoming migraine, including:
•Mood changes, from depression to euphoria
•Increased thirst and urination
For some people, aura might occur before or during migraines. Auras are reversible symptoms of the nervous system. They're usually visual, but can also include other disturbances. Each symptom usually begins gradually, builds up over several minutes and lasts for 20 to 60 minutes.
Examples of migraine aura include:
•Visual phenomena, such as seeing various shapes, bright spots or flashes of light
•Pins and needles sensations in an arm or leg
•Weakness or numbness in the face or one side of the body
•Hearing noises or music
•Uncontrollable jerking or other movements
A migraine usually lasts from four to 72 hours if untreated. How often migraines occur varies from person to person. Migraines might occur rarely or strike several times a month.
During a migraine, you might have:
•Pain usually on one side of your head, but often on both sides
•Pain that throbs or pulses
•Sensitivity to light, sound, and sometimes smell and touch
•Nausea and vomiting
After a migraine attack, you might feel drained, confused and washed out for up to a day. Some people report feeling elated. Sudden head movement might bring on the pain again briefly.
When to see a doctor:
Migraines are often un-diagnosed and untreated. If you regularly have signs and symptoms of migraine, keep a record of your attacks and how you treated them. Then make an appointment with your doctor to discuss your headaches.
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 could indicate a more serious medical problem:
•An abrupt, severe headache like a thunderclap
•Headache with fever, stiff neck, mental confusion, seizures, double vision, weakness, numbness or trouble speaking
•Headache after a head injury, especially if the headache worsens
•A chronic headache that is worse after coughing, exertion, straining or a sudden movement
•New headache pain after age 50
Though migraine causes aren't fully understood, genetics and environmental factors appear to play a role.
Changes in the brain stem and its interactions with the trigeminal nerve, a major pain pathway, might be involved. So might imbalances in brain chemicals — including serotonin, which helps regulate pain in your nervous system.
Researchers are studying the role of serotonin in migraines. Other neurotransmitters play a role in the pain of migraine, including calcitonin gene-related peptide (CGRP).
There are a number of migraine triggers, including:
•Hormonal changes in women- Fluctuations in estrogen, such as before or during menstrual periods, pregnancy and menopause, seem to trigger headaches in many women.
Hormonal medications, such as oral contraceptives and hormone replacement therapy, also can worsen migraines. Some women, however, find their migraines occurring less often when taking these medications.
•Drinks - These include alcohol, especially wine, and too much caffeine, such as coffee.
•Stress - Stress at work or home can cause migraines.
•Sensory stimuli - Bright lights and sun glare can induce migraines, as can loud sounds. Strong smells — including perfume, paint thinner, secondhand smoke and others — trigger migraines in some people.
•Sleep changes - Missing sleep, getting too much sleep or jet lag can trigger migraines in some people.
•Physical factors - Intense physical exertion, including sexual activity, might provoke migraines.
•Weather changes - A change of weather or barometric pressure can prompt a migraine.
•Medications - Oral contraceptives and vasodilators, such as nitroglycerin, can aggravate migraines.
•Foods - Aged cheeses and salty and processed foods might trigger migraines. So might skipping meals or fasting.
•Food additives - These include the sweetener aspartame and the preservative mono sodium glutamate (MSG), found in many foods.
Several factors make you more prone to having migraines, including:
•Family history - If you have a family member with migraines, then you have a good chance of developing them too.
•Age - Migraines can begin at any age, though the first often occurs during adolescence. Migraines tend to peak during your 30s, and gradually become less severe and less frequent in the following decades.
•Sex -Women are three times more likely to have migraines.
•Hormonal changes - For women who have migraines, headaches might begin just before or shortly after onset of menstruation. They might also change during pregnancy or menopause. Migraines generally improve after menopause.
Taking combination painkillers, such as Excedrin Migraine for more than 10 days a month for three months or in higher doses can trigger serious medication-overuse headaches. The same is true if you take aspirin or ibuprofen (Advil, Motrin IB, others) for more than 15 days a month or triptans, sumatriptan (Imitrex, Tosymra) or rizatriptan (Maxalt), for more than nine days a month.
Medication-overuse headaches occur when medications stop relieving pain and begin to cause headaches. You then use more pain medication, which continues the cycle.
Preventive medication is aimed at reducing how often you get a migraine how severe the attacks are and how long they last. Options include:
•Blood pressure-lowering medications. These include beta blockers such as propranolol (Inderal, Innopran XL, others) and metoprolol tartrate (Lopressor). Calcium channel blockers such as verapamil (Calan, Verelan, others) can be helpful in preventing migraines with aura.
•Antidepressants. A tricyclic antidepressant (amitriptyline), can prevent migraines. Because of the side effects of amitriptyline, such as sleepiness and weight gain, other antidepressants might be prescribed instead.
•Anti-seizure drugs. Valproate (Depacon) and topiramate (Topamax) might help you have less frequent migraines, but can cause side effects such as dizziness, weight changes, nausea and more.
•Botox injections. Injections of onabotulinumtoxinA (Botox) about every 12 weeks help prevent migraines in some adults.
•Calcitonin gene-related peptide (CGRP) monoclonal antibodies. Erenumab-aooe (Aimovig), fremanezumab-vfrm (Ajovy) and galcanezumab-gnlm (Emgality) are newer drugs approved by the Food and Drug Administration to treat migraines. They're given monthly by injection. The most common side effect is a reaction at the injection site.
Walkin to the clinic if you find any kind of symptoms.
