I am sorry Nicole for the continuous pain you are in. There are many different causes behind a headache. It may be at times induced by stress, lack of sleep, exhaustion etc, but also related to disorders of the brain, infections, problems related to eyes, ear, teeth, neck etc. Some of those causes can be removed, some can only be eased or reduced in frequency. Being there so many different causes it s difficult to give you a definite answer without examining you. I wouldn t won t to get you panicked, it could simply be a tension type headache, the most common headache disorder, but since you say you ve had this pain for the course of a whole month and you describe it as of a very high intensity, I really think you should be examined by a doctor, preferably a neurologist, to identify the sort of your headache, what causes it and the course of treatment. Our panel will always be here to answer to any other questions you might have. I hope you will feel better soon.
