The main symptom of patients with redness and inflammation in the nasal cavity is particularly pronounced pain in the nose, sometimes accompanied by facial swelling and swelling around the eyes with fever, which must be actively anti-inflammatory. Cefoperazone injection, cefuroxime sodium injection and amoxicillin sodium injection are commonly used clinically to reduce inflammation. Patients with no history of allergy to cefadroxil can apply it, and all need to do skin test before using the drug, and the condition should improve significantly after about 3 days of active treatment. You can also work with Bactrim ointment or compound polymyxin B ointment applied locally in the nasal cavity, which can effectively play the role of anti-inflammatory and swelling. Patients should develop good habits, pay attention to hand hygiene, and do not use their fingers to dig their nostrils at will to avoid the appearance of nasal infections.
