It's been over a year, I think you might want to consider getting some vision therapy.

If your brain has been having trouble interpreting the information from your eyes it can cause dizziness and the other vision related symptoms you refer to.

But so can a hormonal imbalance. A specialist diagnosed me with pituitary malfunction due to a concussion I sustained in an MVA and I've been taking supplemental hormones and my vision has improved a great deal, the horrible dizziness I had that made me "hug the walls" also dissipated and the brain fog has diminished significantly. The treatment has truly been a miracle for me!

But some neck injuries can also cause many of these symptoms too.

Unfortunately trauma like this can potentially damage many different little areas that can all cause similar symptoms.

I'm glad you're still perusing answers and not allowing your GP to bully you into thinking you're nutty. Maybe you should look for a GP who has some experience with concussions?

Please do keep investigating it to figure out what can help you to improve. There are answers out there and there are physicians, specialist and experts who can help.

Because of all the veterans and athletic stars who sustained mTBI's there is a lot of research being conducted and new information is coming out frequently.
