I have researched, and they are used interchangeably, so I'd like to know if there is any paper or article that can illustrate the difference between both on the molecular or cellular level ?
Dear Mostafa E
1. Nasal congestion means the inflammation of the nasal mucosa that finally results in blockage of the nose
2. Rhinorrhea means running nose or flue in common language
3. No difference at cellular levels all pathologies (allergen, virus or bacteria) at nasal mucosal site lead to inflammation and excessive mucosal secretions that flows out we call it rhinorrhea
So Dr.Ashique, in terms of Pharmacological interventions, both are treated the same ?
A runny nose can occur in combination with a stuffy nose, or you might experience a runny nose alone. It's caused by excess mucus production within your sinuses. Normally, your sinuses produce mucus for protection, helping to lubricate and moisturize the delicate tissues in your sinuses, and even trapping harmful particles and germs before they reach the underlying tissues.
If your sinuses start producing too much mucus, though, it starts draining out of your sinuses —and if it drains out your nose, you'll be reaching for tissues to stem the flow. A runny nose can also drain into your throat — known as postnasal drip — which can cause a sore throat, or even make you feel nauseated.
