My head hurts!

I woke up this morning with the most massive headache.  This time it isn't allergy related or anything like that.  Nor did I sleep "funny" as my head hurt a little last night.  I think this is just a plain old headache.  I took some aspirin this morning, but that didn't help.  After class I took some more aspirin, but still no relief.  I even took a nap thinking that might help some, but no.  So, now I am thinking about going running.  Laugh now, but sometimes when I have a headache and go running it goes away.  I wonder if it has something to do with the increase blood circulation, but I'm no medical doctor, so what do I know.  The weather is perfect for a run, cool and cloudy.  If only I had a bit more energy.
