Pain in my head :(

I am not feeling so good today. Yesterday afternoon I started to get a headache which got progressively worse, last night I was awoken by a throbbing pain in the back of my head which has kept me in bed for most of today :( I'm not too sure what the problem is, at first I thought I had pulled something in my neck but now I'm wondering if I have a bit of a something, maybe something flu-like? Although other than the pounding brain and general fatigue, I don't have serious nausea (just lack of appetite). Not sure if I have a temperature as I don't have a thermometer. Anyways, it's all generally not so much fun. I'm drinking lots of water and keeping myself from dying of boredom by listening to scientific american podcasts on my laptop. Here's hoping that I wake up feeling a lot better tomorrow morning!
