A viral infection (the common cold) is the most common cause of a stuffy and/or runny nose, but allergies, influenza, and sinus infections also may cause these symptoms. Less commonly, anatomical obstructions (e.g. a deviated nasal septum, foreign bodies) may lead to nasal congestion.
Common causes of nosebleeds include: 1  Dry, heated, indoor air, which dries out the nasal membranes and causes them to become cracked or crusted and bleed when rubbed or picked or when blowing the nose (more common in winter months) 2  Dry, hot, low-humidity climates, which can dry out the mucus membranes.
