To prevent tension headaches, stay away from activities that strain your neck muscles, such as reading while looking down. Fluctuations in levels of neurotransmitters may also play a role. Your genes may also predispose you to getting migraines. Most people who get migraines have their first attack before age 30. During an aura you may lose your vision or see shimmering, jagged, or flashing lights or colors.
Some people also feel nauseated or irritable right before a migraine begins.
But for frequent or severe migraines, prescription drugs are probably your best bet. Your doctor can help you choose from a wide range, including beta blockers and calcium channel blockers, which keep blood vessels from swelling, and antidepressants, which increase neurotransmitter levels. Acupuncture, relaxation exercises, yoga, biofeedback, and the herbal remedy feverfew can also be helpful. Of course you should also eat regular meals, get plenty of sleep, and avoid foods that trigger migraines for you. Drugs like ergotamine and sumatriptan can help stop a migraine once it starts.
