My father had a chronic subdural hematoma burr hole surgery and was discharged with good recovery after 1week but within few days he became weak and started urinating on bed, taken to hospital back and they said brain need to remain expand and it will be slow recovery. He is most of the time in drowsy state but can  eats food with someone's help. Please help will be recover from this state, he can't move himself nor can speak also now.
