Hi I had fallen from staircase and suffered head injury on 30 Jan 2005, I was in sense and my left eye surrounding was black for around two months, even I don't remember events between 30 Jan - 08 Feb2005. I was treated by a neurologist I recovered from that head injury. But after sometimes I felt I lost my smelling sense. And I am hypertensive taking losartan 25 mg twice in a day. Can my lost smelling sense be cured?
