Man complains about migraine only to find he has had a knife in his brain for FOUR years!! A man who went to the doctor complaining of a headache was shocked to discover he'd had a 4in knife blade stuck in his brain for more than four years.L. F. was stabbed during a robbery four years ago, and the blade of the knife had lodged in his cranium. But despite receiving treatment for his injuries, doctors failed to notice the knife buried deep in the 37-year-old's skull. Incredibly, it wasn't until he visited the doctor last month to complain of his continuous migraines that doctors finally made the grim discovery after a routine X-ray.He underwent an operation to remove the knife and is now in a stable condition in hospital.His surgeon said he had never seen anything so bizarre in his entire career. He said it was a miracle that he could survive being stabbed in the head, let alone survive having the knife lodged in his brain for four years.A true medical miracle.
