Migraine is a neurologic disorder that often causes a strong headache. The headache comes in episodes and sometimes also comes with nausea, vomiting, and sensitivity to light. Migraine is different in everyone.A migraine headache often begins as a dull ache and grows into throbbing pain. The pain can move from one side of your head to the other, can be in the front of your head, or can feel like it’s affecting your entire head.About 80% of people have nausea along with a headache, and about half vomit. Most migraine headaches last about 4 hours, but severe ones can go for more than 3 days. Current thinking is that a migraine likely starts when overactive nerve cells send out signals that trigger your trigeminal nerve, which gives sensation to your head and face. This cues your body to release chemicals like serotonin and calcitonin gene-related peptide (CGRP). CGRP makes blood vessels in the lining of your brain swell. Then, neurotransmitters cause inflammation and pain. There’s no cure for migraines yet. But medications can help prevent or stop them, or keep your symptoms from getting worse. You can also avoid things that trigger your migraines. Lifestyle changes like easing stress and having good sleep habits can help, too. See your doctor any time a headache doesn’t go away or comes back.
