Okay so for the past 2 weeks I've been getting insane headaches all week, almost to the point where I can't think, I get angry quickly (when I'm in pain I get angry for some reason), I don't pay attention in class and it's really starting to take a toll, as I have exams tomorrow and next week. Over Christmas break I had no headache what so ever. But now, I have this, I only get them at school and they go away once I get home around 4:00 PM. Is there any way I can try to solve this issue?
