Interestingly enough, one common cause of bloody mucus in nose areas is high blood pressure. While the blood vessels and the nose seem hardly related in any pertinent way, Kaiser Permanente points out that high blood pressure can cause nosebleeds, which can result in bloody mucus discharge. What can cause this is the perfect storm of adjacent occurrences.
It is a symptom and not a disease. Nasal congestion is the swelling of your nose tissue lining due to filled blood vessels. It can cause nasal drainage of mucus to become congested. Sinus congestion is blood gathering in the lining of air filled cavities in your forehead, cheekbones and behind your nose. This impedes the flow of sinus produced mucus into your nose. Insufficient mucus drainage creates sinus pressure that causes symptoms similar to a headache. Chest congestion occurs when your alveolar walls and lung capillaries become distended with blood. This allows for too much phlegm to collect in your lungs, which causes chest pain and breathing difficulty.
