What is a Runny Nose/Rhinorrea?
Drainage could run down the back of the throat or out of your nose, or both. A runny nose is often referred to by the terms rhinorrhea or rhinitis. Rhinorrhea is actually a thin, mostly clear nasal discharge. Rhinitis is an inflammation of the nasal tissues. A runny nose is often a sign of rhinitis.
Causes of a Runny Nose/Rhinorrea?
One or more of the following possible causes could cause a runny nose:
- Cold temperatures
- Common cold
Gustatory rhinitis is a nonallergic form of rhinitis. It causes a runny nose after eating certain foods.
When to Seek Treatment
Usually, a runny nose will go away by itself. Contact your healthcare provider if:
- You are experiencing symptoms for 10 days or more without any improvement.
- The symptoms are unusual or severe.
- If a child’s drainage comes from one side and is green, bloody, or foul-smelling.
To ensure that the runny nose is not indicative of a more serious condition, your healthcare provider will conduct a physical exam.
