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.
Seek professional care if you experience any of the following symptoms
Generally, Blood in mucus from nose can be related to:
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.
A condition caused by allergens like pollen and dust mites, resulting in a runny nose, stuffy nose, sneezing, and itchy eyes.
Sometimes, Blood in mucus from nose may be related to these serious diseases:
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.
Your doctor may ask these questions to check for this symptom:
