After a concussion I am experiencing the same symptoms (not able to move my forehead/eyebrows) My left eye looks droopier as that was the side of my face that got hit. I am very down about it and still resting as my head still hurts also from the impact. It's been a week since the accident. I just have been told that I hit a nerve and at this point I don't know if my face will go back to normal or if this requires medical attention.
