How is migraine caused?
1Migraine originates deep within the brain
2Electrical impulses spread to other regions of the brain
3Changes in nerve cell activity and blood flow may result in visual disturbance, numbness or tingling, and dizziness
4Chemicals in the brain cause blood vessel dilation and inflammation of the surrounding tissue
5The inflammation irritates the trigeminal nerve, resulting in severe or throbbing pain
