Nasal diseases can be clinically classified into many types, such as inflammation inside the nasal cavity, nasal vestibulitis or boil formation on the mucosa of the nasal cavity, which can be treated by applying Bactrim cream to reduce inflammation. If you have allergic rhinitis or hypertrophic rhinitis, you can consider spraying tretinoin nasal spray and taking oral ketotifen fumarate tablets for anti-allergy treatment. If there is a deviated septum, nasal polyps or papillary growths inside the nasal cavity, surgery is often required to resolve the problem. If there is sinusitis, consider deciding whether to treat it conservatively or surgically to resolve it depending on the symptoms. Patients are advised to go to the hospital for a detailed examination after having a nasal disease to confirm the diagnosis before further treatment.
