Was In A Car Accident 2 Nights Ago. I Was

Was in a car accident 2 nights ago. I was turning Left and his car was in the right lane. He hit my car going 35 or so on the driver side. Taken to hospital and sent home at 1 AM. I had 3 test done, 2 CT scans, 1 of the neck and one of the brain and a chest XRay. Possible concussion. Sent home. Now I am really tired and out of it. When I drive I get dizzy and want to puke. Very unstable on my feet and have arm and shoulder pain on left side and when I move i feel nerve pain down to my hand. I have had spinal fusion of my C5 and C6.
