[|Human|] Hi, My husband passed out and hit the back of his head, he did this Sunday, he has blurred vision in his right eye, he s dizzy at times and his head still hurts at times. He said he had a concussion before and there s nothing they can do, should I be worried?
[|AI|]  Hello ! I read your question and understand your concern. Headache and dizziness are very common after a head concussion. There is nothing to worry about. It is caused by the brain temporary dysfunction. He will recover spontaneously the next days. I would recommend avoiding head trauma for the next month, because a second trauma would cause serious complications. I would recommend painkillers for headaches for some days. If the situation gets worse, and he has severe headache, somnolence or nausea I would recommend you to consult with a neurologist and have a brain CT scan to rule out a late intracranial hemorrhage. Hope to have been of help! Best wishes!
