NASAL POLYPS CAUSES

Some people who are allergic to aspirin develop both asthma and nasal polyps.

Nasal polyps often plug the nose, usually one side at a time. People with allergic rhinitis are so used to having a stopped up nose they may not notice the difference when a polyp develops. Other polyps may be closer to a sinus opening, so airflow is not obstructed, but mucus becomes trapped in the sinus. In this case, there is a feeling of fullness in the head, no sense of smell, and perhaps a headache. The trapped mucus will eventually get infected, adding pain, fever, and perhaps bloody discharge from the nose.
