The first thing you need to do for nasal discomfort is to register for otolaryngology. There are many diseases that cause nasal discomfort, such as nasal vestibulitis, chronic rhinitis, acute rhinitis, deviated nasal septum, nasal polyps, nasal cysts, nasal fibrovascular tumors, chronic sinusitis, sinus cysts, and benign and malignant tumors of the nasal cavity. Clinical manifestations include nasal dryness, pain, nasal congestion, nasal bleeding, yellow nasal discharge, and pus crusting. Patients may also experience fever, headache, toothache, facial swelling, and other related systemic clinical manifestations. A detailed examination of rhinoscopy, sinus CT and nasopharyngoscopy is needed to investigate the internal condition of the nasal cavity before the disease can be diagnosed and, if necessary, surgical treatment is required.
