i fainted this morning and hit the back left portion of my head on my tub, i was only unconscious for a few seconds before i was able to sit back up (i didn t faint from hitting my head, i blacked out before i even began to fall), and it took me a few moments to get my bearings back together but now i only have a mild headache and, of course, the area that i hit still hurts, but i m extremely afraid i might have internal bleeding?
