SYMPTOMS--Generalized or one-sided head pain and possibly nausea, vomiting, and visual disturbances (light sensitivity, bright spots and patterns before the eyes). It might last for days. The first sign is frequent flashes of light or tingling. There may be nausea, vomiting, diarrhea, and cyanosis (blueness) of the fingers from lack of circulation and oxygen. The pain is most common in the temple, but may occur anywhere on the head, face, or neck. The pain is frequently on one side, but it may change to the opposite side, alternate sides, or be on both sides. Migraines usually last 4-72 hours and will be severe, although they could be mild. Some forms of migraines are not associated with headache pain at all and can cause numbness and tingling in the face.
CAUSES--These are caused by a disturbance in the blood circulation. There is alternating constriction and dilation of the blood vessels in the brain, and occurs between the ages of 10-30, more often in women (70%) than men. Food and preservative allergies are frequently the cause. Here are some of the most common causes: food allergy, hormonal imbalance, low blood sugar, tension, depression, too much or too little sleep, changes in barometric pressure, water retention, and menstruation. There often are no migraines during the second and third trimester of pregnancy, or after menopause is past.
Migraines can disappear for years and then reappear. They usually decrease after middle age.
