Definitely good idea to see if it's vestibular function that's off or if it's vision related. I did physical therapy for a year before I finally went to Neuro opthamologist and they diagnosed me with convergence insufficiency meaning my eyes couldnt track objects properly. Tinted glasses helped me immensely. There is a reason you saw Hillary Clinton wear glasses after her concussion. Unfortunately this can be expensive and hard to find dr in this area so people don't think of it for concussion care.

Mark and I disagre about chiropractic care and I am of the opinion that all are quacks and can be dangerous.
