i am a NORMAL human being and i think halohalo is right, its hot outside, then it gets cool inside the house, but my bloody noses always happens at 9A.M. in the morning. I do not pick my nose in severe cases. My dad says i can freeze my blood vessle by putting a piece of ice on my nose. it freezes it, making it come back later, but in a smaller state. I also herad that tilting your head back can be dangerous when you are having a bloody noes, is this true, and if so, what are the effects?
