Blocked, runny or stuffy nose

The blocked, runny or stuffy nose is purely a symptom caused by a multitude of complaints. Whether the discharge be serous or mucoid is not necessarily important, but more so is the transition from mucoid to purulent. Where signs and symptoms of so many causative pathological agents are so similar, a better understanding of nasal function coupled with a more thorough examination of the nasal cavity and indeed of the whole patient, is the only way to come to an accurate diagnosis.
