My daughter for the last several weeks has gotten some really stink sneezes. I asked her doctor and of course he said it was the usual causes like a nasal infection to her breath is stink. When I went back a few days later he told me that he didn't really know what was causing my daughters sneeze to stink. He even did a check up and had my daughter checked by someone else. But they always say the answers I always hear that causes stink sneeze. But there has to be another reason. I also noticed when she sneezes and she can't cover her mouth fast enough and it sprays all over is when it's more noticeable. Do you think AC in cars plays a factor? She does sneeze in the car a lot now and sometimes I have to roll the window down when she sneezes. Even her friend asked me why her sneeze stinks. Is this normal?
