Bonked on the Head, Still Dazed and Confused

So Thursday morning I pulled an Einstein-worthy maneuver by walking into my rising garage door at a brisk clip. UGH. I managed to gash my head open...a small slice in my scalp that sent blood gushing. And of course there was the headache that 2 Darvocets could barely touch. Since I'd survived a particularly hellish head injury 3 years ago, I decided to wait to go to the ER, as I didn't think this incident warranted panic. Still, I've been battling headaches and disorentation for the past 3 days. Of course loved ones inist I should be seen, but really, what will a doctor tell me that I'm not already doing? Rest, icing the noggin, etc... I've got it covered. But damn, my head hurts.
