Hello. Thanks for writing to us at healthcaremagic I will keep a likely possibility of Impetigo. It is a superficial bacterial infection of the skin. Impetigo classically presents as erosive lesions which are covered with honey colored crusts Or dried secretions. The area on the face, about the Nose is particularly prone because of the frequent nasal colonization with the pathogenic bacteria, commonly staph aureus. If I was the treating doctor I would have asked you to take a course of an oral antibiotic e.g either flucloxacillin Or cephalexin for a week. Oral antibiotic sare prescription medicines, therefore I will suggest you to talk to your physician for the needful. Topically you may use an OTC topical antibacterial e.g 2% mupirocin ointment, twice daily. Regards
