Dry nose is mostly caused by too dry air, fire, etc. Treatment would require topical nasal medications that can keep the nasal cavity lubricated, such as vegetable oil and liquid paraffin. At the same time, diet and work and living habits should also be adjusted. Dry nose is common in young and middle-aged people, and the main symptom is dryness in the nose, little snot and sticky and not easy to discharge, forming scabs or blood crusts, and a few may have dryness in the nasopharynx and pharynx. Next is nasal bleeding, because the nasal mucosa is dry, the mucosal capillaries are brittle and cracked, very small damage can also cause nasal bleeding, such as blowing the nose, coughing, sneezing and so on. Some will also have a prickly nasal sensation, and patients often like to rub their noses, pick their noses and blow their noses to remove the dry crust in the nose. For treatment, the first thing is to thoroughly improve the working and living environment and strengthen protection according to the cause of the disease. Secondly, some vitamins such as vitamin A, vitamin B, vitamin C, etc. should be appropriately supplemented. Topical nasal drops of compound mint nasal drops, liquid paraffin, vegetable oil, etc. can be applied to the nasal cavity. Or you can also apply gentamycin or erythromycin ointment, which can not only lubricate the nasal cavity, but also anti-inflammatory and antiseptic. Insist on daily nasal rinsing to keep the nasal cavity clean and moist. Drugs that dilute mucus and promote the movement of mucous membrane cilia in the nasal cavity, such as Genoton, also have a good therapeutic effect on dry nose. Never touch or pick your nose casually when it is dry, otherwise it will lead to more bleeding in the nasal cavity. If the above methods still can not relieve the symptoms, it is best to go to the hospital in a timely manner. (For specific medication, please refer to the doctor’s guidance in an interview)
