Not an advice forum: This forum is not for medical advice. Most people get a headache at some time, such as from colds, infections, lack of sleep, too much driving, long hours on the computer, stress at work, etc... Sometimes, one's doctor may recommend Tylenol (acetaminophen) or other over-the-counter medications temporarily. A bad or increasing headache should be examined by one's doctor, especially in pregnancy.
