A migraine headache can cause intense throbbing or a pulsing sensation in one area of the head and is commonly accompanied by nausea, vomiting, and extreme sensitivity to light and sound.
Migraine attacks can cause significant pain for hours to days and be so severe that all you can think about is finding a dark, quiet place to lie down.
Some migraines are preceded or accompanied by sensory warning symptoms (aura), such as flashes of light, blind spots, or tingling in your arm or leg.
Medications can help reduce the frequency and severity of migraines. If treatment hasn't worked for you in the past, talk to your doctor about trying a different migraine headache medication. The right medicines, combined with self-help remedies and lifestyle changes, may make a big difference.
Migraine headaches often begin in childhood, adolescence or early adulthood. Migraines may progress through four stages, including prodrome, aura, headache and postdrome, though you may not experience all the stages.
Less commonly, an aura may be associated with limb weakness (hemiplegic migraine).
When to see a doctor
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:
Although much about the cause of migraines isn't understood, genetics and environmental factors appear to play a role.
Migraines may be caused by changes in the brainstem and its interactions with the trigeminal nerve, a major pain pathway.
Imbalances in brain chemicals — including serotonin, which helps regulate pain in your nervous system — also may be involved. Researchers continue to study the role of serotonin in migraines.
Serotonin levels drop during migraine attacks. This may cause your trigeminal system to release substances called neuropeptides, which travel to your brain's outer covering (meninges). The result is headache pain.
Migraine headache triggers
Several factors make you more prone to having migraines.
Sometimes your efforts to control your pain cause problems.
Also, some people experience complications from migraines such as:
Preparing for your appointment
You're likely to start by seeing your primary care provider, but you may be referred to a doctor trained in evaluating and treating headaches (neurologist).
Because appointments can be brief, and because there's often a lot to talk about, it's a good idea to be well prepared for your appointment. Here's some information to help you get ready for your appointment, and what to expect from your doctor.
What you can do
Your time with your doctor is limited, so preparing a list of questions will help you make the most of your time together. List your questions from most important to least important, in case time runs out. For migraine headaches, some basic questions to ask your doctor include:
In addition to the questions that you've prepared to ask your doctor, don't hesitate to ask questions during your appointment.
What to expect from your doctor
What you can do in the meantime
Tests and diagnosis
If you have migraines or a family history of migraine headaches, your doctor trained in treating headaches (neurologist) will likely diagnose the condition on the basis of your medical history, a review of your symptoms, and a physical and neurological examination.
Your doctor may also recommend a variety of tests to rule out other possible causes for your pain if your condition is unusual, complex or suddenly becomes severe.
Treatments and drugs
Migraines can't be cured, but doctors will work with you to help you manage your condition.
A variety of medications have been specifically designed to treat migraines. In addition, some drugs commonly used to treat other conditions also may help relieve or prevent migraines. Medications used to combat migraines fall into two broad categories:
Choosing a strategy to manage your migraines depends on the frequency and severity of your headaches, the degree of disability your headaches cause, and your other medical conditions.
Some medications aren't recommended if you're pregnant or breast-feeding. Some medications aren't given to children. Your doctor can help find the right medication for you.
Preventive medications can reduce the frequency, severity and length of migraines and may increase the effectiveness of symptom-relieving medicines used during migraine attacks.
Your doctor may recommend that you take preventive medications daily, or only when a predictable trigger, such as menstruation, is approaching.
In most cases, preventive medications don't stop headaches completely, and some drugs cause serious side effects. If you have had good results from preventive medicine and your migraines are well controlled, your doctor may recommend tapering off the medication to see if your migraines return without it.
To prevent or reduce the frequency of your migraines, take these medications as your doctor recommends:
Lifestyle and home remedies
Self-care measures can help ease the pain of a migraine headache.
Nontraditional therapies may be helpful if you have chronic migraine pain:
Whether or not you take preventive medications, you may benefit from lifestyle changes that can help reduce the number and severity of migraines. One or more of these suggestions may be helpful for you:
