The symptoms of rhinitis are sneezing, runny nose, nasal congestion or recurrent headache, and some patients may even experience smell disturbance. If the mucous membrane of nasal cavity is highly edematous and the blood vessels are dilated, there is a possibility of blood in the nasal discharge, which will be improved after standard treatment. Of course, special attention should be paid to the fact that some nasal mucosa with blood, repeatedly does not heal, and even has symptoms such as post-aspiration blood, etc. It should be noted that nasal, sinus and nasopharyngeal examinations must be done to exclude benign or malignant nasal tumors, such as involute papilloma, malignant tumors of the sinuses, nasopharyngeal cancer or fungal infection of the sinuses, hemorrhagic necrotic polyps and other diseases.
