What does a polyp in the sinus cause?

A polyp in the sinus can cause a range of symptoms, including nasal congestion, difficulty breathing through the nose, and a reduced sense of smell. It may also lead to sinus infections due to blockage of the sinus passages. Additionally, polyps can contribute to facial pain or pressure and may cause persistent sinusitis if left untreated. Regular medical evaluation is recommended to manage symptoms and prevent complications.
