CLaired please find a good concussion clinic around your area, if you are willing to spend money go to UPMC Concussion Clinic in Pensylvania. Its about $1000 for an appointment but they will give you a full test telling you what your deficits are and what you can do to make them better. Don't sit around and wait as people are saying here to do. Go get some diagnostics, balance tests, vestibular-ocular exam, convergence insufficency test instead of killing yourself with anxiety as that is what happens when you sit around too long waiting for something like this to go away..

There are concussion clinics around that give rehab to fix balance, and vision using exercises to rehab your injury. Also, its good to be under a concussion clinics care while going through this process.
