Hi, I understand your concern and I ll try to help you. According to what you reported, there are no warning signs after head trauma that your husband suffered. The warning signals after a head injury are loss of consciousness after the trauma, feeling of nausea, episodes of vomiting, dizziness, progressive worsening of the head pain, altered behavior, confusion, excessive sleepiness. It is important that you be alert to the appearance of any of these signs and if they appear, you must immediately seek emergency care. Emergency care should look for fractures and intracranial bleeding as subdural hematoma, subarachnoid hemorrhage, epidural hematoma, and even cerebral concussion. Therefore, although no alarm signals currently be under surveillance and search a hospital in case of appearance of any of these warning signs above. Hope I have answered your question. If you have any further questions I will be happy to help you. Wish you good health.
