There are two main conditions to consider when living with a patient who is prone to rotting their nose. In the first case, the patient’s nasal cavity may be particularly dry, and there is often a large number of crusts formed in the nasal cavity. This is often caused by a decrease in the secretion function of the nasal mucosa, or a particularly dry working or living environment. Because of the large amount of crust formation in the nasal cavity, the patient will feel uncomfortable in the nose, and will often dig the nostrils with the hand, which will easily lead to the appearance of rotten nose. For treatment, physiological sea saline or compound menthol nose drops should be sprayed in the nasal cavity, which can effectively play a moisturizing role. In the second case, it is mainly considered that the patient is picky about food, does not like to eat fresh vegetables and fruits, and the body lacks a lot of vitamins, which is especially easy to lead to the mucous membrane of the nasal cavity not to heal. In terms of treatment, patients can eat more fresh vegetables and fruits, and need to supplement vitamin B or vitamin C.
