Symptoms may last from a few hours to a day or two. The vision changes of the aura usually disappear as the headache begins. There is no single test to confirm migraine headaches. Your doctor will base the diagnosis on your symptoms, medical history, and physical exam. A careful headache history is the most helpful diagnostic tool.
Treatment depends on the frequency and severity of headaches.
Rest and sleep often help the headache significantly. Your headache diary may suggest that specific foods or activities trigger your headaches. If your migraine headaches are severe and recurring, you may need to take medication regularly to prevent the headaches from starting. Several medications can be taken on a regular basis to prevent headaches. Another type of treatment is to prevent a severe headache by taking medication soon after the migraine begins.
