The factors that lead to this are: Drinking plenty of water and steam inhalation can help reduce sinus problems. However, if you have pain or fever that lasts for more than two weeks, it is essential to see an ENT doctor for treatment. Nasal sprays can also be used as directed by your doctor to clear sinus blockages.
1. Infections
The most common cause is a viral infection like a cold or flu. This causes the lining of the sinuses to swell and block the flow of mucus. In some cases, bacterial and fungal infections can also cause this.
2. Allergies
Allergies to dust mites, pollen, pet dander, and pollution can cause the lining of the nose to swell and produce excess mucus. This is called allergic rhinitis.
3. Nasal Polyps
Polyps are soft growths that form inside the nose or sinus cavities. They block the flow of fluid from the sinuses and cause mucus to build up inside, causing infection.
4. Deviated Septum
If the septum that separates the two nostrils is deviated or deviated to one side, it can block the sinus passages on one side. This causes mucus to build up.
5. Pollution and Smoking
Airborne smoke, strong odors, and cigarette smoke slow down the activity of the cilia (small hairs that help remove mucus) in the nose. This causes the mucus to stay inside.
6. Reduced immunity
Chronic sinus problems are often seen in people with weakened immune systems and diseases such as diabetes.
Symptoms:
Severe pain and heaviness in the forehead and under the eyes.
Nasal congestion, difficulty in recognizing smells.
Dark-colored mucus coming from the nose or throat.
Headache and slight fever.
