I've had blood when I blow my nose on/off for about 4 months now. I don't blow excessively and sometimes when i avoid blowing my nose and get a runny nose as a result, there is still blood. Sometimes it's bloody mucas (red/brown), sometimes pure blood in clear mucas and sometimes small clots. I'm a 25 year old female - blood pressure is fine, smoker, slightly overweight but healthy otherwise. I had a bad cold in November when this first started and I was also sicking up pure blood and coughing up blood/blood clots with green and clear mucas which is when the problem started with blowing my nose so I just put it down to infection but this seems to be happening every couple of weeks! Is this normal?
