When patients have the symptoms of yellow nasal discharge with blood, it is often due to the condition of bacterial infection in the nasal cavity and sinus area, and the nasal mucosa will be affected by inflammatory factors, causing local erosion, rupture and a small amount of blood oozing, so it further leads to the symptoms of yellow nasal discharge with blood. In this case, patients need to use antibiotic medication in time to reduce the production of yellow purulent nasal discharge from the root cause of infection, which is conducive to the improvement of local nasal mucosa congestion, swelling, and erosion and rupture, and to reduce the exudation of bloody secretions. Some patients may have abnormal growth of nasal cavity and sinuses, which need further comprehensive judgment through nasal endoscopy and imaging examination of the nose.
