I have been experiencing headaches since friday afternoon last week. these headaches would come and go from time to time?

Doctor can examine: 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 try over-the-counter drugs like Tylenol, Motrin, Aleve, Excedrin, or their generic brands. A bad or increasing headache, recurring headache (like this case), weird headache, or one with other worrisome symptoms should be checked.
