Headaches

There are two kinds headache disorders:

The first is based on symptoms (called primary headache disorders) and includes migraine, tension-type headache and cluster headaches.

The second is based on their causes (called secondary headache disorders). This would include headaches associated with a head injury, stroke, substance misuse and/or their withdrawal (including alcohol), infection, disorders of the neck, eyes, nose, sinuses or teeth.

Migraine is a type of headache that is often localized in a certain area of the head and is sometimes accompanied by a pronounced sensitivity to light and sound. Other common migraine symptoms include nausea and vomiting.  Some migraines are worsened by head motion, sneezing, straining or physical exertion.
