hi, I hit my head at work around 10 pm, it hurt pretty bad and i felt a little dizzy and saw black for a second when i got up. I feel fine now and have a bump, i dont want to wake my parents up to take me to the ER, especially if it s nothing. I hit my head on the top and like i said there is a bump and the whole top of my head is a little soar. My boss said the usually with head injuries if you get a bump thats a good sign because its probably and external injury rather than internal, but he also isn t a doctor. Does it sound like something that is ok?; Or even something that can even wait till the morning? Thanks.
