i have a bit of insite to offer....post concussion syndrome is really just a head injury which causes a bursting of a membrane inside the inner ear, namely the oval window or round window....which then causes the vestibular system to malfunction giving one a host of strange symptoms related to the peripheral and autonomic nervous systems manfunctioning and also vestibular sensory disturbance. doctor's just call things a syndrome when they can't figure it out...i have had surgery to fix the tear in the membrane but most people heal on thier own with bedrest, no valsava maneuvers/no straining lifting etc. and also with supplementation of wound healing accelerators like b vitamins & iron. best of luck you will heal if you allow your body the rest it needs
