Headache
A headache, or cephalalgia, is a sensation of discomfort or pain that can occur in any part of the head, scalp, or neck. It can vary in intensity, duration, and frequency, from mild and fleeting episodes to severe and chronic ones. Headaches are very common and can have various causes, some of which are relatively benign and can be treated with simple measures, while others may indicate a more serious underlying medical condition.
