Home -> Shop By Store -> MigraineMigraineWhat is MigraineA migraine is a very common, but very particular, type of headache. Most people who get migraines have repeated attacks of headaches that occur over many years. The typical migraine headache is throbbing or pulsating, and often is associated with nausea and changes in vision. While many migraines are severe, not all severe headaches are migraines, and some migraines can be quite mild. Causes of Migraine Despite years of research, scientists do not know exactly why migraines occur. The pain of migraines almost certainly results from swelling in blood vessels and nerves that surround the brain. This swelling probably is triggered by changes in brain chemicals and electrical activity in a primitive part of the brain known as the brain stem. Symptoms of Migraine A migraine usually is a throbbing headache that occurs on one or both sides of the head. The headache typically is accompanied by nausea, vomiting or loss of appetite. Activity, bright light or loud noises can make the headache worse, so someone having a migraine often seeks out a cool, dark, quiet place. Most migraines last from four to 12 hours, although they can be shorter or much longer. One unique feature of migraines is an unusual sensation that a migraine is about to occur. Diagnosis of Migraine Computed tomography (CT) or magnetic resonance imaging (MRI) scan of the brain usually will be normal. However, your doctor may recommend additional testing if your headaches have features that are not typical for migraines, or you develop other worrisome symptoms. |
