In the human body, what is the more common name for rhinorrhea?

Rhinorrhea or rhinorrhoea is a condition where the nasal cavity is filled with a significant amount of mucus fluid. The condition, commonly known as a runny nose, occurs relatively frequently. Rhinorrhea is a common symptom of allergies (hay fever) or certain diseases, such as the common cold. It can be a side effect of crying, exposure to cold temperatures, cocaine abuse or withdrawal, such as from opioids like methadone. Treatment for rhinorrhea is not usually necessary, but there are a number of medical treatments and preventive techniques available.

The term was coined in 1866 and is a combination of the Greek terms rhino- ("of the nose") and -rhoia ("discharge" or "flow").
