If you battle the menstrual migraine monster, you’re definitely not alone. In fact, according to a paper released just last year, “Menstrually related migraine (MRM) affects about 20% of female migraineurs in the general population.” In other words: menstrual migraines are no joke.

While there’s still quite a bit of research underway, doctors have been able to pinpoint some of the causes and, consequently, some treatments. We spoke to Dr. Linda Girgis and Dr. Curtis Glade to get the run down.

The When

While it’s not always the case, menstrual migraines often occur about two to three days before your period starts (PMS). Once your period actually starts, you’ll usually experience relief, especially several days into menses, says Dr. Glade.

The timing, of course, varies depending on the individual. You may also experience headaches during ovulation, which is about a week before PMS and two weeks before menses. More http://tiponhealth.com/battle-menstrual-migraines/
