I Had A Closed Head Injury In August And I

I had a closed head injury in August and I suffered a concussion and I am still dizzy, nauseated and have left facial and scalp pain constantly. It is not getting better and I had a CT on Friday Oct 21 and have not heard a thing. I am suffering on going headaches, blurred vision in one eye and generally have no quality of life any more. This is causing me to suffer on going depression and feel this will never get better.
