Woke up, sneezed, and there was blood. Has anyone had something like this? Is it normal or from what could cause blood in the nose to stay? It's not bleeding. Could the humidifier be on? It was similar a month ago, waking up and there were bloody flakes for some reason. Yesterday evening, my nose didn't breathe and I got baby drops, but before that, I never had such a strong sneeze with blood.
