Nasal congestion is not necessarily a cold. Cold medicine has many symptoms, with nasal congestion being one of them. However, there could be more reasons for nasal congestion. A cold is just one factor causing nasal congestion. Other reasons might include chronic rhinitis, acute rhinitis, sinusitis, deviated nasal septum, and nasal polyps. Often, these conditions are primarily due to pathological changes in the nose itself. Therefore, it is recommended to visit an otolaryngology clinic, particularly for persistent nasal congestion, and consider undergoing a nasopharyngoscopy. If needed, a sinus CT may also be considered, along with symptom assessment and additional diagnostic tests, to make a more comprehensive and accurate evaluation.
