Itchy and painful nose may be related to acute rhinitis, nasal vestibulitis, nasal eczema and other causes. 1. Acute rhinitis: the stimulation of bacterial and viral infections can cause swelling and congestion of the mucous membrane and increased secretion, resulting in nasal pain and itching. 2. Nasal vestibulitis: manifested as redness and swelling of the skin in the nasal vestibule, with obvious pain when touched, which may be accompanied by obvious itching. 3. Nasal eczema: If eczema occurs in the nasal skin, it can be characterized by paroxysmal itching, and once excessive scratching leads to erosion and ulceration, it can cause pain. It is recommended that people with itchy and painful nose go to the regular hospital in time to clarify the cause of the disease and standardize the treatment under the guidance of the doctor.
