Migraine headache pain is often described as an intense throbbing or pulsating pain in one area of the head. Additional symptoms include nausea and/or vomiting and sensitivity to light and sound. Approximately one third of individuals who suffer from migraine also experience aura shortly before the migraine. An aura can appear as flashing lights, zig-zag lines, or a temporary loss of vision. Migraines can often be triggered by various factors including stress, hormone changes, bright or flashing lights, lack of food or sleep and diet. Migraine is three times more common in women than in men and affects more than 10% of people worldwide.
Although the true root of migraine is still unclear, according to The Migraine Research Foundation, researchers believe that it has neurological roots related to chemical imbalances. Migraines can last between 4 and 72 hours. The most common symptoms include nausea, vomiting, dizziness, sensitivity to light, sound, and touch.
