###Human: How can nasal blockage with mucus be treated? ###Assistant: Hello. Nasal congestion is aggravated by polyps as they cause blocked nasal pathways mechanically. Endoscopy is necessary to understand at what extent the polyps are enlarged to decide for the best treatment strategy. Mucus is trapped and should be on its way to get cleared. But polyps are making it difficult. So continue medication as prescribed and run endoscopy as suggested.
