Itchy patches lasting for 6 months may be due to fungal infection, eczema, allergy, psoriasis, seborrheic dermatitis, dry skin, or a steroid-modified fungal infection. Creams like Keto B and Candid B contain antifungal medicine along with steroids, and while they may reduce itching temporarily, repeated use can sometimes change the appearance of fungal infection and make it harder to clear completely. When skin patches keep returning or spreading despite treatment, the exact cause may need to be confirmed properly. Doctors sometimes advise skin scraping tests or examination under special light to identify fungal infection more accurately. Treatment may include pure antifungal creams, oral antifungal medicines, moisturisers, anti-allergy medicines, or treatment focused on eczema or psoriasis, depending on the diagnosis. Keeping the skin dry, avoiding tight clothing, reducing sweating, and not sharing towels may help if a fungal infection is involved. Thick scaling, pus, severe redness, fever, or rapidly spreading patches can indicate more severe skin inflammation or infection and may require more focused skin treatment.
