For many months, you have been using a cream that contains corticosteroid (
anti-inflammatory,
anti-pruritic and vasoconstrictive substance), antibiotic, and anti-fungal agents without any diagnosis looked into and established. It is recommended to see a dermatologist who will most likely advise discontinuation of mentioned topical therapy for seven days, then evaluate clinical status of the skin, and perform other necessary diagnostic tests prior to prescribing optimal treatment.
