After a bump on the head, it is important to make sure that the treatment options are specific to each case. Because some people are very mild and just need to rest and recuperate at home, while others are very serious and may need to be treated by way of surgery, or even have respiratory and circulatory disorders that result in death, each one is different. In terms of the lightest, if it’s just simple dizziness and headache, it could be Traumatic Brain Injury Response Syndrome, and basically with rest at home and with timely nutritional supplementation, basically it will get better in 7 days. If the accompanying coma is greater than 5 minutes, but less than half an hour, it may be a concussion, then you need to carry out a CT examination of the head, if necessary, oral medication for symptomatic treatment. If the coma lasts for more than half an hour, with nausea and vomiting, there is a possibility of a cerebral contusion, which requires hospitalization. If the coma is more severe and persistent, it may be a more serious condition such as subdural hematoma or epidural hematoma, which needs to be relieved and treated by surgery.
