My daughter has had a headache since yesterday night i have given her panado but it seems she is worse because she has been sleeping for hours ?

Many possibilities: Most people get a headache at some time, such as from colds, infections, lack of sleep, long hours on the computer, stress at school, etc... Temporary over-the-counter options include Tylenol, Motrin or Advil, and their generic brands. A bad or increasing headache, recurrent headache, weird headache, or with other worrisome symptoms, should be checked by her primary care doctor.
