If you’ve experienced a head injury, you should get medical treatment right away. If you were seen by a doctor after the accident but were discharged, it’s still possible that you’ll suffer delayed symptoms after the head injury. It’s best to get to a doctor as soon as possible if you spot the subtle signs of traumatic brain injury, or even if you’re just concerned about the severity of the blow to the head. Treatment for traumatic head injuries can range from pain medication and rest to brain surgery and extensive rehabilitation.
