Hi There My Daughter Who Is 11 Hit Her Head

Hi there my daughter who is 11 hit her head earlier on the side of the door and very shortly after wards had a big soft limp on the back of her head, this was a this afternoon it is now late and she still complains it is sore and that she can't sleep on it, it is sore to touch. Am not sure whether to take her to the hospital or wait till the morning and take her to the doctors?. X
