Rhinorrhea (runny nose) is a very common symptom. It most often happens due to allergies and viral infections (like a cold or the flu). But several other conditions can make your nose drip. A runny nose typically goes away on its own, but certain treatments can improve it.
Cold temperatures
When you breathe in through your nose, your nose warms the air and adds moisture to it as it goes down into your lungs. Cold, dry air irritates your nasal lining. In defense, your nasal glands produce excess mucus to keep the lining moist, resulting in a runny nose.
Shedding tears (lacrimation)
When your body produces excess tears (such as from crying or an irritant in your eyes), the tears drain through the inner corner of your eyelids, through the nasolacrimal duct and into your nasal cavities. These tears can drip out of your nose and stimulate mucus production, leading to more nasal discharge.
Sinus infection (sinusitis)
Bacterial infections, viral infections and allergies can irritate your sinuses, causing them to get blocked and filled with fluid. This can cause pressure and pain in your face, nasal congestion and a runny nose with thick yellow or green mucus.
Nasal polyps
Nasal polyps are painless and benign (not cancerous) growths inside your nose and sinuses. As they grow, they can cause a runny nose and other symptoms.
In conclusion, Rhinorrhea typically runs its course. There’s nothing you can do to immediately stop it. It usually goes away in time. But certain at-home remedies and medicines may provide some relief. All news are gotten from Cleaveland.
