i have been having headaches for the past couple of weeks. it is behind my eyes, my forehead, and the base of my head and neck. sometimes i even feel sick to my stomach with them. i am not sure what is bring them on but they can last for hours and i have to go to sleep for them to go away. i am really thinking about going to the drs because of them. they seem to get worst at night. does anyone have any idea what it could be or what i could take?
