Hello. Thanks for writing to us at healthcaremagic From your description it seems like you have a condition known as Erythema Multiforme (EM). In EM there are targetoid lesions with central necrosis, edema and peripheral red rim. There may be fluid filled lesions if inflammation is intense. The lesions are commonly distributed on arms, legs and face. It is a type of hypersensitivity reaction to various triggers, most commonly Herpes Simplex Virus in people who have a history of cold sores. Treatment is with topical steroid+antibiotic cream combination and once daily Oral antihistamine e.g cetrizine 10 mg once daily. In those cases who are preceded by an episode of cold sores, a course of an antiviral is also warranted. Since the leson on your nose is also discharging yellowish fluid and had crusted lesions therefore likely it has developed secondary bacterial infection. In view of that I would also suggest a week of an oral antibacterial for a week e.g either flucloxacillin Or cephalexin. I would suggest that you visit a dermatologist in your region for a confirmatory diagnosis as well as appropriate treatment. Regards
