My wife heat the left side of her head on the window visor as she got in the car. No bruises or bumps, bleeding, etc. She did fall a sleep / passed out for few minutes. We were in the mountains and it took about 30-40 minutes to get home. Only treatment as been an ice pack which has had some relief. She is able to walk, slowly, up and down stairs and to take a shower. The Pain is still there but the ice has helped? Is there anything I need to be alert to?
