Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with a doctor.
Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.
What you describe could be a migraine, but more information is needed to diagnose. Migraine is in the category of primary headache disorders. Primary headache disorders are much more common than secondary ones. Migraines are classically described as a pulsating throbbing one-sided pain with nausea and discomfort in bright lights that lasts several hours to days. It can be quite disabling. However, there are other types of primary headache disorders. Additionally, it is important to have secondary causes of headaches ruled out. These may include sleep apnea, intracranial lesions, etc. Without further information about your headache, it is difficult to provide you with adequate information. However, it is important for you to understand that if you have not experienced headaches in the past and you are now having new head pains, seeing a neurologist is a good idea, just to make sure there is nothing serious causing this pain. Imaging of the brain and sometimes then neck may be indicated depending on your exact symptoms, your physical examination, and other factors.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
