Headaches are a common health concern characterized by pain or discomfort in the head, scalp, or neck. They can range from mild to severe and may be caused by stress, dehydration, tension, sinus issues, hormonal changes, or underlying medical conditions. Common types include tension headaches, migraines, and cluster headaches, each with distinct triggers and symptoms. Management involves identifying and addressing the cause, staying hydrated, maintaining proper sleep, managing stress, and, when necessary, using medications or medical interventions to relieve pain and prevent recurrence.
