Headache, sleeplessness, chills, muscle pain?

Details unclear but: 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... Some people temporarily try OTC Tylenol (acetaminophen), Motrin, Advil, Aleve, or Excedrin for partial relief. A bad or increasing headache, recurrent headache, weird headache or one that won't go away should be examined by a doctor.

Sounds viral: hydration and rest, if high fever or not beginning to better in a few days call PCP or urgent care indicated. Best Wishes
