Nasal mucous membrane damage caused by rhinitis, sinusitis, nose picking, etc. is mild, only the surface of the mucous membrane is damaged, and the body’s immunity is normal, it can be repaired by itself. 2. If the nasal mucosal damage caused by nasal tumor, nasal polyp, etc. is due to the invasive effect of the nasal mass. If no timely intervention is given, the broken mucosa is difficult to heal and recover. 3. If the mucous membrane is damaged and infected, and the immunity of the body is relatively low, the mucous membrane damage can lead to prolonged healing, and generally can not be recovered by themselves. It is recommended that patients go to the hospital to check the cause of nasal mucosal damage, and actively standardize the treatment under the guidance of the doctor.
