Can rhinitis caused by nose picking heal on its own?
In general, whether rhinitis caused by nose picking can heal on its own depends on the extent of damage. Mild mucosal irritation usually resolves spontaneously, while cases involving infection or chronic inflammation are unlikely to self-resolve and require medical intervention. Detailed analysis is as follows:

If nose picking only causes minor mucosal injury or dryness in the nasal cavity, resulting in temporary symptoms such as nasal congestion or itching without purulent discharge, the nasal mucosa can typically repair itself once nose picking stops. Using saline solution to moisten the nasal cavity can aid recovery, with most cases healing within about a week.
However, frequent nose picking may lead to repeated mucosal damage and bacterial infection, causing symptoms like yellow nasal discharge, worsened nasal congestion, and pain inside the nose, which may progress to chronic rhinitis. In such cases, the mucosa's healing capacity is impaired and requires treatment with nasal sprays to reduce inflammation, along with proper local hygiene to prevent the spread of infection.
To prevent recurrence, avoid the habit of nose picking. When the nasal cavity feels dry, use a humidifier or apply mild petroleum jelly. Clean the nasal cavity using saline irrigation instead of sharp objects. Wear a mask outdoors to reduce irritation from dust and other airborne particles.
