What do headaches everyday mean? could it have to do with medicine i have been on for years? side effects now?

Hard to guess: 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 OTC options (not for chronic use) include Tylenol, Motrin or Advil, Aleve, Excedrin and their generic brands. A bad or increasing headache, recurrent or persistent headache (as in this case), or with worrisome symptoms needs evaluation.
