The recovery time for patients with nasal mucosal injury cannot be generalized, as it may take about 1 week to heal in milder cases and 1-2 months to recover in more severe cases. Recovery time from nasal mucosal injury is closely related to the severity of the injury and whether symptomatic treatment is taken. As the nasal mucosa is delicate, dry air or upper respiratory tract infection, allergic rhinitis, etc. can damage the mucosa, resulting in mucosal erosion and bleeding, congestion, swelling and pallor. If the damage area is small, in the absence of inflammation and wetness, generally about 1 week can gradually recover. If the damage to the nasal mucosa is large and the trauma is deep, it usually takes about 2 weeks to 1 month to gradually recover if active anti-infection treatment is carried out; in dry or inflammatory conditions, it may be difficult to repair for 1-2 months. The nasal mucosa needs to be kept moist during the repair period. If there is inflammation, the inflammation should be actively controlled and nose picking should be avoided as much as possible. At the same time, avoid eating spicy and irritating food, and eat more vegetables and fruits to facilitate recovery.
