A migraine is a primary type of headache that can often be described as severe pounding, throbbing pain. The pain is moderate to severe and can last from four hours to three days if left untreated. It can be so severe that it interferes with your daily activities. The pain can be associated with nausea, vomiting, and sensitivity to light.
Several environmental factors such as dehydration, skipped meals, sleep disruption, hormone fluctuations, and exposure to chemicals could trigger a migraine headache. Migraine attacks can also be associated with a problem in the electrical impulses within the nervous system and post-traumatic stress disorders. Stressful events can lead to an increase in attack frequency. If migraine attacks happen frequently, the migraine is defined as Chronic Daily Headache.
