Getting daily horrible headaches?

Lately, as in the past 2 or 3 weeks, I have been having really bad headaches. I hate any noise when I usually can't stand silence, and all I want to do is turn off the lights and lay down face first. I am currently working on my planner, it's been a fairly calm day. But I find myself resting my head and closing my eyes every few minutes to help the headache. My brother is talking in the room next to me and it seems louder and it's annoying me more than usual. I also feel tired for no reason. I got 10 hours of sleep, there isn't a reason for me to be tired. It's not like a pulsing pain or anything, but my head just feels terrible. I've been getting awful hot lately has well, and it's been in the 40s everyday. Help?
