So last night (almost 24 hours ago) I had slipped in the middle of the night, and hit my forehead super hard on what I think was my stereo. It's just kind of swollen and of course there's a bruise. (Right above my left eyebrow). It wasn't until tonight that I got this sort of throbbing headache. Its on the top left side of my head. Not particularly near where I hit. I'm sure ive gotten a headache like so before, but ive been reading, and other places say "Get to the ER, you might have a brain injury!" Gee thanks, that makes me feel good. What do you think?
