Migraine Headaches (cont.)
IN THIS ARTICLE
Experts aren't sure what causes migraines.
They run in families, and experts have found a genetic link. But it isn't clear why some people get migraines and others don't.
Certain things can bring on a migraine. These are called triggers. Your triggers may be different from someone else's. Having several triggers increases the chance you will get migraines.
Some common triggers include:
The most common symptom of a migraine headache is a throbbing pain on one side of your head. You also may have other symptoms before, during, and after a migraine. Different people have different symptoms.
Symptoms before the migraine begins
A day or two before a migraine starts, you may feel:
Symptoms of an aura
About 1 out of 5 people has a warning sign of a migraine called an aura. It usually starts about 30 minutes before the headache starts. During an aura, you may:
Symptoms when the headache starts
Symptoms can include:
Less common symptoms include:
If you have these less-common symptoms and have not had them before, call your doctor right away so that he or she can make sure you aren't having a transient ischemic attack (TIA), stroke, or other serious problem.
Without treatment, a migraine headache can last from 4 to 72 hours.
Symptoms after the headache
After the headache stops, you may have muscle aches or feel very tired. These symptoms may last up to a day after your migraine ends.
Types of migraines and their symptoms
You may have one or more types of migraine headache. Each type has its own features. For example, some people get migraines with an aura. Some get them without an aura. Some women get menstrual migraines, which happen before, during, or shortly after their menstrual period.
It can be hard to tell the difference between a migraine and another type of headache, such as a tension or sinus headache. You may think that you have sinus headaches. But it's more likely that they are migraine headaches if they happen often and interfere with your daily life.
Migraines can occur along with many other health problems, such as asthma or depression. More serious conditions, such as tumors or infections, can also cause migraine symptoms. But most headaches are not caused by serious health problems.
