Most headaches can be diagnosed by a medical history and physical exam. To rule out other causes of headaches such as an aneurysm, tumor, or structural abnormality, a doctor may call for vision tests, X-rays, a CT scan, MRI, a lumbar puncture, or an EEG.
Other health conditions keep you from taking preventive drugs.
Those drugs could mix badly with other medicines you take.
You prefer treatments that don't involve meds.
If you can't take medication or prefer not to, there’s also a device you and your doctor could consider. It's called Cefaly, and it’s the first FDA-approved machine that prevents migraines in people over 18. Worn around your forehead, this portable headband-like device gives out electrical impulses. These stimulate a nerve connected with migraines. You’ll feel a tingling sensation and should use it once a day for 20 minutes.
If You’re Pregnant
Your headaches may ease up during your second and third trimesters.
If you have severe migraines, your doctor may suggest that you first try a treatment that’s not a drug -- such as biofeedback, relaxation therapy, or stress-management training. He may also recommend a preventive drug that has the lowest risk possible.
Talk to your doctor about the risks and benefits of taking preventive medications for migraines. Together, you can decide the best approach for you.
