what are reasons for migraine headaches
Migraines may be caused by changes in the brainstem and its interactions with the trigeminal nerve, a major pain pathway. Imbalances in brain chemicals â including serotonin, which helps regulate pain in your nervous system â also may be involved. Researchers are still studying the role of serotonin in migraines.

Weatherâchanges in humidity, temperature, and air pressureâis one of the most common migraine triggers, and one of the hardest to control. Changes in sleep.
