My daughter fainted and hit the back of her head hard on cement. At first there was a golf sized lump. A few hours later it was gone. She has a mild head ache, feels a bit woozy and had a low grade fever the last few days, which she says is making her feel woozy and sounds are a bit dim but not terrible. We went to the ER. The golf sized lump is gone and we are home. At the hospital they said her hematocrit was a little low 32. She just finished her period and is 19 years old. is there any concern of internal bleeding?
