Medications

Many medications can cause headache (usually not migraine) as a side effect. A few medications increase the risk of migraine because
of the way they interact with brain neurotransmitters.

It is commonly known that foods can trigger migraine headaches. But did you know that there are many non-food triggers? A recent
poll conducted by the World Headache Alliance asked "What is the most significant factor preventing you from effectively managing
your headaches?" Most people indicated that it was the inability to manage stress and other lifestyle factors.
