Headache

What is it? 
 A painful sensation in any part of the head, ranging from sharp to dull, that may occur with other symptoms. 
 Most headaches are minor, and you can treat them with a pain reliever. Some headaches, however, signal a dangerous or serious medical problem. Don't ignore headaches that aren't explained or headaches that steadily worsen.
