Hi, I wonder if you can advise me please. After a really busy day, and probably not eating properly. I began to run, the next thing I know, I saw a bright light as the right side of my face hit the floor. I must have hit the underside of my chin first, rolled a little and hit my face. The grazes and brushing are healing, but I can feel, but not see, an intermittent flutter in the right side of my neck. I am fit, active and healthy 59 year old who has never smoked.
