What are migraine headaches?
Migraines are painful, throbbing headaches that last from 4 to 72 hours. When you have a migraine, it may be so painful that you aren't able to do your usual activities. But migraines can be treated. And even though they make you feel bad, they don't cause long-term damage.
Symptoms of a migraine can include:
- Throbbing pain on one side of the head. But you can have pain on both sides.
- Pain behind one of your eyes.
- Moderate to very bad pain. The pain may be so bad that you can't do any of your usual activities.
- Pain that gets worse with routine physical activity.
- Pain that gets worse when you're around light, noise, and sometimes smells.
Other symptoms include nausea, vomiting, or both.
What causes migraine headaches?
The cause of migraines isn't fully understood. Experts believe that changes in the activity of brain cells may lead to inflammation in certain nerves, which causes pain.
Migraines often run in families, so genetics may play a role for some people.
Some things can cause a migraine to start. These are called triggers. Your triggers may be different from someone else's. Having several triggers increases the chance that you will get migraines.
Some common triggers include:
- Not eating.
- Poor sleeping habits.
- A change from your normal routine.
- Red wine.
- Monosodium glutamate (MSG).
- Strong odors.
Preventing migraine headaches
You can do things to help prevent migraine headaches. Try these tips.
- Keep a daily headache diary.
It can help you find out what triggers your migraines.
- Avoid your migraine triggers.
Triggers include changes in daily routine, foods, hormones, medicines, lights, odors, or other things in the environment. Triggers add up. So the fewer triggers you have at one time, the better your chance of preventing a migraine.
- Live a healthy lifestyle.
- Get regular sleep.
- Eat healthy foods at regular times.
- Avoid alcohol and drugs.
- Avoid foods that may trigger your headaches.
- Get regular exercise.
But be careful to not push yourself too hard. It may trigger a headache.
- Take medicines that prevent migraines.
- Don't take medicine for headache pain too often.
Talk to your doctor if you are taking medicine more than 2 days a week to stop a headache. Taking medicine too often may cause medicine-overuse headaches.
- Find healthy ways to cope with stress.
Migraines are most common during or right after stressful times. Try finding ways to reduce stress like practicing mindfulness or deep breathing exercises.
- Ask your doctor about trying herbs and supplements.
Some people find that magnesium and riboflavin (vitamin B2) help prevent migraine headaches.
- Try acupuncture or biofeedback.
Some people find that these can help reduce how many migraines they have or how bad the migraines are.
How are migraine headaches diagnosed?
To diagnose migraines, your doctor will do an exam and ask questions about your personal and family history. Your doctor will ask how many headaches you have, how long they last, and what symptoms you have. There are no tests that can diagnose migraines.
Migraines can be hard to diagnose. Their symptoms are like those of other types of headaches. For example, many people have been diagnosed with sinus headaches when they actually have migraines.
It's likely that you are having migraine headaches if they happen often and interfere with your daily life.
Your doctor will decide if you need to have tests to find out if your headaches are caused by another health problem. You may have an MRI, a CT scan, or a lumbar puncture.
How are migraine headaches treated?
You can't cure migraines. But you can use medicines and other treatments to feel better. Finding and avoiding the things that trigger your headaches may also help.
The goal of treatment is to reduce how often you get migraines and to stop the headaches with the fewest drug side effects.
For mild to moderate migraines, you may first want to try over-the-counter pain relievers. They have fewer side effects. And they cost less than other medicines. But if they don't help, you may need prescription medicines.
Your doctor may prescribe medicines to stop or to prevent a migraine.
If treatment doesn't help your migraines, you and your doctor may make changes. You may try different medicines, a new mix of medicines, or different doses. Sometimes, treatments that don't use medicines are tried. It may take some time to find the right treatment to help you.

Close your eyes, and try to relax or go to sleep. Don't watch TV or read.
