Long-term unilateral nasal congestion may be caused by nasal tumor or other diseases such as deviated nasal septum, nasal polyps and so on.
There are many reasons for long-term unilateral nasal congestion, which may be caused by nasal tumors, such as nasopharyngeal fibrous hemangioma, nasopharyngeal carcinoma, etc. Typical symptoms are nosebleed, nasal congestion, nasal congestion on one side, and the symptoms usually worsen in a persistent manner.
