Migraine is a severe type of headache, but generally does not last long and usually does not come with symptoms of limb weakness or nausea and vomiting. It often resolves on its own after a few hours, even without treatment. Typical migraine attacks often have some precursory symptoms related to vision changes, such as blurred vision, distorted shapes, or the appearance of water-like ripples; these symptoms are followed shortly by headaches, either on one side or both sides of the head. Migraines do not generally have a major impact on one's health. During an attack, taking ibuprofen sustained-release capsules can help alleviate the pain. Additionally, it is recommended to avoid staying up late and overworking. Certain foods, such as pickled products, salty vegetables, and nitrates, can trigger migraines; some dairy products and red wine can also provoke headaches, so it is best to avoid these foods to prevent migraines.
