Nasal polyps are associated with irritation and swelling (inflammation) of the lining of your nasal passages and sinuses that lasts more than 12 weeks (chronic sinusitis). However, it's possible to have chronic sinusitis without nasal polyps. Nasal polyps themselves are soft and lack sensation, so if they're small, you may not be aware you have them. Multiple growths or a large polyp may block your nasal passages and sinuses. Common signs and symptoms of chronic sinusitis with nasal polyps include:  A runny nose Persistent stuffiness Postnasal drip Decreased or absent sense of smell Loss of sense of taste Facial pain or headache Pain in your upper teeth A sense of pressure over your forehead and face Snoring Frequent nosebleeds
