About the Symptom
Nasal mucus sometimes can be mixed with bloody drainage from one or both sides of the nose (see blood from nose). This can be common and due to nasal trauma or dryness but can be serious if recurrent or if large amounts of blood are present. Medical attention should be sought in these settings.
When to See a Doctor
Seek professional care if you experience any of the following symptoms
- Head injury
Possible Causes
Generally, Blood in mucus from nose can be related to:
- Sinusitis
Infection of the sinuses, which are cavities around the nose and face. The infection can be acute (lasting about a week) or chronic (lasting more than three months). Most often infections start as a viral upper respiratory infection (URI) and then bacterial infection sets in. The symptoms include fever, facial pain or pressure, and nasal obstruction or drainage. Imaging including CT scans may be necessary.
- Allergic Rhinitis / Allergic Conjunctivitis (Including Spring Catarrh)
A condition caused by allergens like pollen and dust mites, resulting in a runny nose, stuffy nose, sneezing, and itchy eyes.
Related Serious Diseases
Sometimes, Blood in mucus from nose may be related to these serious diseases:
- Cerebrospinal Fluid Rhinorrhea
Cerebrospinal fluid (CSF) rhinorrhea is a condition where CSF, the fluid surrounding the brain, leaks into the nose and sinuses. Common causes include head trauma, sinus or skull base surgery, or increased pressure inside the skull and brain tissue. In some cases, the leak is spontaneous and the cause is unknown. Headache is a common accompanying symptom.
- Leukemia
Doctor's Diagnostic Questions
Your doctor may ask these questions to check for this symptom:
- Do you have thin, bloody nasal discharge?
- When did you first notice your runny nose?
- How often do you experience a runny nose?
- Regarding your runny nose, how frequently do you blow your nose each day?
- How is your runny nose now?
