Fever and a thick, discolored nasal discharge are signs of acute sinusitis, a short-term sinus infection usually caused by viruses or bacteria. Other symptoms include nasal congestion, postnasal drip that is worse at night, and bad-smelling breath that is unrelated to dental problems. Sometimes, sinus pain can feel like a toothache. The most common symptom is painful pressure in upper parts of the face, especially in the forehead, behind the nose, between or behind the eyes, or in the cheek. People with asthma, cystic fibrosis, or immune system problems develop chronic sinusitis more often than others. Chronic sinusitis also can be seen in people whose sinuses and nasal passages are structurally abnormally narrow. Polyps, nasal tumors and nasal fractures can obstruct the sinus drainage leading to chronic sinusitis. These allergies trigger the release of histamine and other chemicals that cause the inner lining of the nose to swell and block sinus drainage. In adults, chronic sinusitis most often is linked to nasal swelling caused by allergies, especially allergies to inhaled dust, mold, pollen, or the spores of fungi. The buildup of mucus leads to increased sinus pressure and facial pain. Drainage from the sinuses can be obstructed by structural abnormalities of the nose, infection, or tissue swelling caused by allergies. Normally, the sinuses drain through small openings into the inside of the nose.Īnything that obstructs that flow can cause a buildup of mucus, and sometimes pus, in the sinuses.
