Migraines are severe, recurring and painful headaches. They can be preceded or accompanied by sensory warning signs and other symptoms.
The extreme pain that migraines cause can last for hours maybe even days.
According to the American Migraine Association, they affect 36 million Americans, or approximately 12% of the population.
Migraines can follow an aura of sensory disturbances followed by a severe headache that often appears on one side of the head. They tend to affect people aged 15 to 55 years.
