Full title: A 44-year-old man went to the hospital after pus began oozing from his chest, where doctors discovered a knife that had been embedded in his body for eight years. According to the report, he showed no signs of chest pain, breathing problems, coughing, or fever, and was otherwise in good health.
The article says a stabbing. I struggle to imagine it too, but maybe a fall while it was still protruding, like you say.
