You had stated in your other post that the ER doc had given you more explanation etc. than others; you might give him a call, and ask if he knows of a Physiatrist or Neurologist more in tune with Concussions / PCS than the one you are currently seeing. And explain your previous attempts with Dr. Cantu's group already, since you did not suffer a Sport's injury.

Mark has directed you to a very good starting point for recovery; also check the links on the top of these threads and look into the one's from the Lawyer for more information; as well as Brainline.org.

All very helpful in getting started toward understanding and recovery .....

Best Wishes .....
