Headache: bad.
Headache where you can't tell if it's sinus pressure or tension or migraine: very bad.
Headache where see above but the upshot is it hurts so much you're sick to your stomach: :-( :-( :-(
Right now putting the heating pad on the back of my neck is helping a little bit, so I'm going with tension and assuming that the heat is loosening things up and getting some blood to the brain where I want it. That's probably totally not what's happening, but it makes sense to me and my complete lack of medical training, and - more importantly - makes me feel a little better, so I'll take it.
