To figure out what brings yours on, print the list below. Then check any possible triggers at the first signs of a headache. Review the list every few weeks or months to see if you can spot a pattern. Chances are, the items that get the most checks are your triggers.
There is no specific test to diagnose a migraine headache. If you seek help from your health care provider for recurring headaches, you may be asked to keep a headache diary in which you record information about symptoms leading up to a headache, symptoms of the actual headache, and possible triggers that may have provoked the episode.
Your health care provider will want to take a careful history to determine any patterns to your headaches and to learn whether such headaches run in your family....
