I hit my head on a door (not the corner just the edge) today around 2 pm. It was near my right temple but not exactly on it. It hurt like hell for a few minutes but then went away and I forgot about it. An hour later, I went sailing and felt a little nausea, which I thought was strange because I normally do not get sea sick, but I didn't make the connection. Then, hours later as I was getting ready to go to sleep, I lightly touched the spot and hurt fairly badly. Now I have a slight headache in the spot (which could be caused by my mild hypochondria) but it seems to hurt even more when I lie down. I'm worried its internal bleeding
