Yeah , but its been 4 years since injury and by the way i once went to neurologist and said that i block stutter in my speech and im fluent when alone , she replied but you aren’t blocking now! I knew instantly she had no idea what stuttering was and its inconsistency . When i told her i am fluent when alone , she sent me to psychiatrist , he sent me to a speech therapist again Should i still be seeing a doctor 4 years after head injury to clear any doubts? But interesting thing was that i didnt feel anything of some sort that victims of concussion typically face for example headaches , confusion , dizziness , memory problems , vomiting etc . But it was just blocking stammer that showed up next day at school!
