What causes a migraine without aura?

ANSWER

Scientists aren't sure what causes migraines. They think that many  chemical  such as– serotonin, calcitonin gene-related peptide, and dopamine -- play a role. According to the theory, a wave of nerve cell activity spreads across the brain and excites the trigeminal nerve. This excitation causes the release of a variety of neurotransmitters which caused a change in the size of the blood vessels releasing more neurotransmitters and ultimately causing an inflammatory process and pain. brain
