Typical migraine attacks start with prodromal symptoms. Common prodromal symptoms include blurred vision, distorted vision, or the appearance of water-like patterns. Shortly after these symptoms disappear, headache symptoms on one side of the head appear, often accompanied by nausea and in a few cases, vomiting. These symptoms can subside completely within a few hours and can recur. The occurrence of migraines is greatly related to diet, such as pickled foods and leftovers that contain nitrates, which can trigger a migraine attack. It is best to avoid these, as well as cheese and red wine which can also trigger migraines. During a migraine attack, symptomatic oral pain relievers can be used for treatment. (Please use medication under the guidance of a professional physician.)
