What is rhinorrhea commonly known as?

Rhinorrhea is commonly known as a "runny nose," characterized by a clear nasal discharge. It often occurs due to various conditions such as allergies, colds, or sinus infections, where inflammation or irritation of the nasal passages leads to excessive mucus production. The term itself is derived from Greek roots meaning “flow” and “nose.” Recognizing rhinorrhea as clear nasal discharge is essential in clinical practice because it helps differentiate between various types of nasal symptoms and directs appropriate treatment choices. Other symptoms, such as severe headache, chest pain, and ear congestion, although they may be associated with respiratory or sinus conditions, do not accurately define rhinorrhea.
