Just rang the QMC Major Trauma department and got to speak to a doctor who checked my records again and when asked if I have been diagnosed with TBI or brain injury they said no. Been told that it's only the frontal bone and left eye bones that have been fractured and are currently healing.
Not sure if a good news or not, but guess they wouldn't be lying to me as guess if it was brain injury they would have mentioned it as this hasn't been revealed by the CT scan.
