I have been having horrible headaches for about 4days straight it literally is there from when i wake up to when i sleep. i do wear glasses at computer and i just had my script renewed so that's ruled out. i think i'm stressing abit at work.

Doctor can examine: Most people have a headache at some time, such as from colds and flus, lack of sleep, too much driving, long hours on the computer, stress at school, etc... OTC options include Tylenol, Motrin, Aleve, Excedrin, and their generic brands. A severe headache, recurrent or persistent headache (as in this case), weird headache, or one with other worrisome symptoms should be evaluated now.
