Concussion w/ TBI Medical Expenses

In February I got a concussion or TBI (tramatic brain injury) while at work. It didn't seem terrible at first but I haven't been able to really go out in public or do much of anything without headaches, dizziness, and mostly just feeling like I'm walking and thinking in fog. I was sent to Cognitive FX by workers compensation, but now they are saying that it's too new of a treatment for them to put me through their program. I was faced with hoping they cover it and get help now or wait until August for them to figure something else out. At this point, even if this treatment works, I could still lose my job because I have been on "disability" so long.  Please help us out if you can.
