[|Human|] I hit the front of my head hard on the wall yesterday as I was putting something away.  This morning I have a terrible headache, vomitting and when I move my head I get a sensation that goes along the side of my head to my neck.  Should I be worried, I feel alert?
[|AI|]  Hello, THX to contact us. I understand your concern. If I am your doctor I advise you that head injury followed by vomiting and headache is a sign of intracranial hemorrhage, creating pressure on the brain. It is necessary to do CT scan of the brain to rule out hemorrhage. If the there is an alteration in consciousness kindly attend the nearby ER department otherwise condition will be fatal. I will be happy to answer more of your concerns, kindly know me, Wish you a very good health at Chat Doctor. Chat Doctor. Infectious Disease.
