I normally have a headache i haven't checked it ,should i be worried?

Many possibilities: 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... Over-the-counter options include acetaminophen, Motrin or Advil, Aleve, Excedrin Migraine, plus their generic brands. A bad or increasing headache, recurrent headache, weird headache, or one with other worrisome symptoms must be seen by a Dr.
