Migraine: What is it?
Migraine is a particular form of headache or headache. It differs notably headache “ordinary” by its duration, intensity and various other symptoms.
The headache often begins with a pain on one side of the head or located near an eye. The pain is often perceived as pulsations in the cranium. Migraine can also impair vision and cause nausea and vomiting.
Special surprisingly, some migraines are preceded by physiological events which are grouped under the name Aura. Auras are essentially visual effects which may take the form of flashing lights, rows of brightly colored or a temporary loss of sight. After 15 to 30 minutes, these symptoms disappear. Then comes the headache.
