i have had a headache for about the past 3 days. i take pain relievers and they help a little, but the pain just never really goes and stays away. its seems like every time i enter a bright room, look at something bright, or hear something loud and obnoxious, the pain gets worse. sometimes i dont even want to wake up in the morning because i am scared of the pain that the day will bring. what are some ways that i can get rid of this ever-lasting pain? also, what are some thins that might be causing them?
