Spraying blood out of the nose may be caused by acute rhinitis, nasopharyngeal carcinoma, acute sinusitis and other diseases.
1. Acute rhinitis: this disease is mainly caused by respiratory viruses, mostly adenovirus, rhinovirus, influenza virus, etc. It can also be secondary to bacterial infections such as Streptococcus pneumoniae and Haemophilus influenzae. Patients will have symptoms such as watery nasal discharge and nasal bleeding, so they will spray blood when spraying nasal mucus.
2. Nasopharyngeal cancer: the occurrence of this disease is mainly related to EBV infection, followed by heredity, environment, improper diet and so on. Generally, there is no symptom in the early stage of the disease, but with the further development of the disease, patients will have bloody nasal discharge, which can be manifested as spraying blood out of the nose. There will also be tinnitus, nasal congestion and other symptoms.
3. Acute sinusitis: the causes of this disease include inflammation of the nasal cavity, facial trauma, infection of neighboring tissues, etc. Common symptoms include nasal congestion, runny nose, etc. Some patients may have a little blood in their runny nose.
