Sinus

Sinusitis means your sinuses are infected or inflamed. Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen, this can block the sinuses and cause pain and infection.

Sinusitis can be acute, lasting for less than four weeks, or chronic, lasting much longer. Acute sinusitis often starts as a cold, which then turns into a bacterial infection. Allergies, pollutants, nasal problems and certain diseases can also cause sinusitis.

Symptoms of sinusitis can include pain, fever, weakness, fatigue, cough and congestion. There may also be mucus drainage in the back of the throat, called postnasal drip, which can cause a tickly cough, especially at night when lying down.

Treatments include antibiotics, decongestants and pain relievers. Using heat pads on the inflamed area, and saline nasal sprays can also help.
