Has anyone ever called you a pain in the neck? I know I have been called that a few times in my life but that is not what we are talking about. Head pain or often called an ache, can be the result of many different factors. Not enough sleep, too much alcohol, or a high level of stress at work or in the home can lead to this uncomfortable state of being. Sometimes there does not seem to be much you can do about it but if it is because of alcohol consumption, drink more water. The pain is caused by dehydration.
