Sores in Nose: 15 Common Causes & What to Do

Sores in the nose can appear for many reasons, like allergies, rhinitis, or frequent and prolonged used of nasal sprays. These sores can cause scant nasal bleeding and dryness within the nostrils. Scabs often appear due to mild conditions that are not serious and relatively easy to treat.

If you notice sores or wounds in the nose that do not improve with time, or if these sores frequently emerge, you should see a doctor for assessment and treatment, which will depend on the underlying cause of the sores.

What causes nose sores?

Sores in the nose can appear for the following reasons:

What to do: It is important to ensure adequate levels of humidity in your home. You can do this by using a humidifier. You should also drink plenty of water throughout the day to ensure hydration. 

2. Prolonged use of nasal sprays

Using nasal decongestant sprays for prolonged periods can dry out the nasal airways and lead to the formation of sores. Overuse may also have a rebound effect, in which the body produces even more nasal secretions. This may increase inflammation in the nasal tissue. 

What to do: You should ideally only use medicated nasal sprays for up to 5 days. You can swap these for natural, hypertonic saline solutions, which are hypertonic and often made with sea water. 

3. Scratches

Scratches within the nose can be caused by a domestic pet, such as a cat or dog, and can cause wounds in the nostrils that dry and create scabs.

What to do: You are advised to keep the area clean by applying  saline or soap and water using a cotton swab. Then be sure to let it dry and avoid touching it to promote prompt healing.

4. Sinusitis

Sinusitis is an inflammation of the nasal sinuses that is associated with symptoms such as headache, runny nose and a feeling of facial pressure.

Excessive nasal discharge caused by this disease can cause irritation of the nasal passages and the formation of wounds inside the nostrils.

5. Allergies

Allergies are one the most common causes of inflammation within the nasal airways. They can be triggered following contact with animal fur, dust or pollen, for example, and can make the nasal tissue lining more fragile and susceptible to the formation of sores. Blowing your nose constantly can also irritate the skin around and within the nose, which can lead to dry skin and scabs. 

What to do: You should identify the underlying trigger causing the allergy so that it can be avoided. Anti-histamines, as prescribed by a doctor, can help to relieve symptoms, as well as adequate fluid intake. Performing vapor inhalations and staying in humid environments can also help to keep the nose skin hydrated, preventing further sores from appearing. 

6. Irritating chemicals

Some chemicals, like abrasive cleaning products, industrial chemicals or cigarette smoke, can also irritate the nose and cause sores. In most cases, contact with chemicals can also respiratory symptoms, like coughing and difficulty breathing.

7. Weak capillaries

Capillaries are the smallest blood vessels in our body and, when they weaken, they become very fragile and can rupture. This ca lead to small bleeding points on the skin or injuries to different parts of the body, such as the nose.

Furthermore, weak capillaries can also cause purple spots, or bruises, on the skin. Read more about what can cause easy bruising.

9. Injuries

Mild injuries, like rubbing, scratching or hitting the nose can damage the delicate skin within the nostril. This can lead to bleeding and the formation of scabs. Small children tend to insert small objects into their nose, which may also result in bleeding.

What to do: It is important to treat the injury and wounds to prevent injection. Sores should be kept clean with water and a mild soap, and you should avoid picking at scabs to promote adequate healing. 

10. Drug use

Inhaling drugs like cocaine or poppers can cause bleeding and serious injury to the internal nose. These drugs can dry out the mucosa, which can lead to sores that are difficult to heal. 

What to do: Drug use should be avoided and the internal nasal skin should be kept hydrated by drinking plenty of water and using a humidifier. 

11. Piercing

In addition to the injury to the nose caused by the piercing itself, any friction or pulling at the piercing site can also cause wounds or injuries to the nose.
