The first and most immediate danger caused by nose-picking is that it can lead to vesicular inflammation of the nasal mucosa. Repeated inflammatory irritation can lead to nasal vestibulitis, which in many people is accompanied by nasal bleeding. If the inflammation is repeated, it may eventually lead to eczema-like changes in the nasal vestibule, which can cause itching as well as allergic symptoms. Picking the nostrils can lead to loss of nasal hairs in the anterior part of the nose. A nasal vestibule that loses nasal hairs may reduce the filtration of bacteria and the clearing of allergic substances, which can lead to symptoms such as allergies, sneezing, and a clear runny nose.
