Tingling/numbness to the back of my head?

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 Tylenol, Motrin or Advil, Aleve, Excedrin, and their generic brands. A bad or increasing headache; recurrent, persistent, or weird headache; or with other worrisome symptoms needs a doctor's exam.
