An itchy and painful nose indicates that the patient’s nose is infected with bacteria, often caused by the patient blowing his nose hard or having bacteria in his hands but often touching his nose repeatedly, and sometimes the patient has boils forming in the nasal cavity. Patients are advised to first apply cold towels or ice packs to the nose, which can effectively reduce the swelling and the sensitivity of the nasal mucosa or the skin of the nose. At the same time, you can apply Bactrim ointment or compound polymyxin B on the nose to effectively play the role of anti-inflammatory, swelling and anti-itching, and the patient’s itchy and painful situation should be significantly improved after active treatment. Patients should pay attention not to blow their nose with their hands often, and not to always dig their nose with their hands to avoid nasal infections.
