When describing migraine symptoms it first helps to understand what is a migraine.A migraine is not just an ordinary headache, as those who suffer from it will know only too well.
A migraine headache can be severe and persistent and is accompanied by a wide range of other symptoms.
Migraines are the result of a constriction of the arteries in the brain, which reduces blood flow to the brain.
This is followed by dilation or widening of these arteries. Hence the often unique throbbing sensation experienced with a migraine headache.
