Happened a year and a half ago and still suffering with various symptoms and been to many, many specialists, therapies, meds etc., and not much help. My symptoms got severe only after a month with near
passing out and went down hill after that.
They put this collectively under Post Concussion Syndrome and there is no specific treatment but lot of other alternative treatments out there and tried quite a few and helped only a little bit (neurofeedback, HBOT, vision therapy etc.,) .
