As per your clinical presentation and your past history of head injury
its evident that many structures in the head was traumatised...nerve vessels also were injured..
contains many nerve endings its obvious such major head injury have caused severe damage to the nerve tissue which are permanent..as you nerve tissues are responsible for all senses...
therefore you are having such symptoms only because of definite nerve damage
...you do visit a neuro physian for further evaluation and treatment
