What is sinuses?What are its causes?
Answers
Answer:
Sinusitis is usually caused by a virus and often persists even after other upper respiratory symptoms are gone. In some cases, bacteria, or rarely fungus, may cause a sinus infection. Other conditions such as allergies, nasal polyps, and tooth infections can also contribute to sinus pain and symptoms.

Answer:
The sinuses are a connected system of hollow cavities in the skull. The largest sinus cavities are about an inch across. Others are much smaller. Your cheekbones hold your maxillary sinuses (the largest). The low-center of your forehead is where your frontal sinuses are located.
Explanation:
Chronic sinusitis can be caused by an infection, growths in the sinuses (nasal polyps) or swelling of the lining of your sinuses. Signs and symptoms may include nasal obstruction or congestion that causes difficulty breathing through your nose, and pain and swelling around your eyes, cheeks, nose or forehead.
Common symptoms of sinus infection include:
Postnasal drip.
Discolored nasal discharge (greenish in color)
Nasal stuffiness or congestion.
Tenderness of the face (particularly under the eyes or at the bridge of the nose)
Frontal headaches.
Pain in the teeth.
Coughing.
