Migraine or Headache?
A migraine is more than just a bad headache
Although the exact cause of migraine headaches isn't completely understood, medical researchers believe that migraine headaches are caused by altered blood flow and abnormal levels of naturally produced substances in the brain. When certain arteries dilate, blood flow is increased and cause pain producing chemicals to be released. Additionally, the dilation causes an increase in the natural substance levels, such as prostaglandins and serotonin. This makes the blood vessels lining the brain swell and creates pressure on nearby nerves. These nerves send pain signals to the body that are typically felt around the eye or temple region and can extend to the face, sinus, jaw, or neck. 1 2
Your migraines may be inherited
If someone in your family gets migraine headaches, then it's not surprising you get them as well. That's because the abnormalities in the brain that can lead to migraines appear to be genetically inherited.3 In fact, 70% to 80% of people who get migraines have a family history of the disorder.2
Migraines vs. tension headaches
According to the U.S. Department of Health and Human Services, migraines tend to be more severe than tension headaches. 1
