Should I See a Doctor?

I've had a headache for 11 days, I've noticed it's for the most part in the same place. I have had someone suggest that it could be my glasses, But I've had my glasses for over a year. Also, I have waken up to this headache. That can't possibly be enough time for enough eyestrain to cause a headache. Suggestions of the cause? Should this be worrisome?
