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.
If you have frequent nosebleeds, you could have a more serious problem. Dry air is the most common cause of nosebleeds. Living in a dry climate and using a central heating system can dry out the nasal membranes, which are tissues inside the nose.This dryness causes crusting inside the nose.Crusting may itch or become irritated.requent nose blowing is another cause of nosebleeds. Other common causes of nosebleeds include: 1  foreign object stuck in the nose. 2  chemical irritants. 3  allergic reaction. 4  injury to the nose. 5  repeated sneezing. 6  picking the nose.
