What does it mean when you have a nosebleed from the right side?

Right-sided nosebleeds may be caused by dry nasal mucosa, external irritation, right-sided rhinitis, right-sided sinusitis, or right-sided vestibulitis. Symptoms can be improved through methods such as cold compresses to stop bleeding, avoiding irritants, and medication. If nosebleeds occur frequently or involve heavy bleeding, prompt medical attention is necessary.

1. Dry nasal mucosa: Dry environments or insufficient fluid intake can cause dehydration and fragility of the right nasal mucosa, making blood vessels prone to rupture and leading to nosebleeds, which are usually mild. It is recommended to use saline nasal sprays to moisten the mucosa, increase daily water intake, and use a humidifier indoors to maintain proper humidity levels.

2. External irritation: Forceful nose-blowing, picking the right nostril, or nasal trauma can damage blood vessels inside the nasal cavity and cause bleeding, possibly accompanied by mild nasal fullness or pain. Avoid aggressive nose-blowing and nose-picking. During a nosebleed, keep the head forward, apply a cold compress to the bridge of the nose, and gently press the nostrils to stop the bleeding.

3. Right-sided rhinitis: Viral or bacterial infections can trigger inflammation in the right nasal cavity, causing mucosal congestion and swelling, which makes blood vessels more likely to rupture, resulting in nosebleeds along with nasal congestion and runny nose. Under medical guidance, medications such as mometasone furoate nasal spray, *Biyuan Tongqiao Granules*, or loratadine tablets may be used to relieve symptoms.

4. Right-sided sinusitis: Sinus infection leads to increased nasal discharge on the affected side, irritating the mucosa and causing congestion, erosion, and bleeding, often accompanied by headache and purulent nasal discharge. Patients may take cefixime dispersible tablets, oxymetazoline hydrochloride nasal spray, or *Sinusitis Oral Liquid* under a doctor’s supervision to alleviate discomfort.

5. Right-sided vestibulitis: Inflammation of the nasal vestibule occurs due to irritation from secretions or mechanical friction, leading to mucosal erosion and bleeding, often associated with local pain and crusting. As directed by a physician, topical antibiotics such as erythromycin ointment, chlortetracycline hydrochloride ointment, or oral cephalosporin antibiotics like cefalexin capsules may be used to improve symptoms.

To prevent recurrence, maintain nasal moisture and avoid frequent irritation. Blow your nose gently, eat a light diet rich in fruits and vegetables, drink plenty of water, and avoid spicy, hot foods to reduce the risk of nasal blood vessel congestion.
