I appreciate your responses more than you can know. As I stated, witnessing the event, knowing my son (well adjusted, happy, strong student), and reading so much on the internet about PCS has floored me as to this doctor's response and dismissal.

His balance is so off that he is unable to stand, much less walk, unassissted. I don't mean just a little...he cannot stand up straight and sways like crazy. The neuro "tests" this doctor did contradicted this.
Has anyone else heard of balance problems this severe?

The doctor did not test his vision issues. He turned out the room lights and looked into the back of his eyes. Yet, my son cannot read due to the letters being scrambled.

Your responses have been the first "help" we have been able to locate and I am holding on to them like a lifeline. Thank YOU!
