Every year when the weather is cold, or in an air-conditioned room, I have a runny nose, feel uncomfortable and sleepy, but taking cold medicine can alleviate it!

A stuffy nose means that there is something in the nose that hinders breathing and makes air circulation difficult. There are many reasons, such as runny nose or sneezing when catching a cold, acute rhinitis, allergic rhinitis and so on. If there is purulent nasal discharge, it may be purulent leakage. In addition, the curved nasal septum separating the nasal cavity, hypertrophic rhinitis with thick turbinate and sinusitis with purulent paranasal sinuses can all cause nasal congestion.

If nasal congestion becomes a long-term chronic symptom, it will be more difficult to treat. Because of nasal congestion, breathing is changed to mouth, which is easy to cause laryngitis. In addition, stuffy nose can also make people lose concentration and cause obstacles in their work.

Although nasal medicine can relieve the symptoms of nasal congestion, it is easy to become habitual and the symptoms will be aggravated.
