Maybe I'm just built different because c-diff doesn't affect me that much. For me, it's melena, because I literally still smell it for hours after my shift has ended.
Also, while maybe not the worst smell, one of the somehow more disturbing ones was when an intestinal blockage patient belched and it smelled like a fart... which basically it was.
Kidney stones. I've passed three of them and the last time my wife called an ambulance because I couldn't get off the floor. Think I'll go drink some water...
