When I was cleaning my nose with a suction device, mucus came out along with blood. We have a runny nose and I've been cleaning it with a suction device constantly, and when I saw blood, I didn't continue. Now there is a little bit of blood mixed with mucus in my nose. What should I do? Should I clean my nose so that the blood comes out or is this dangerous?
