It is not uncommon for fungal infections to persist, especially if previous topical treatments contained steroids, which can sometimes prolong the infection. Since oral itraconazole was unsuccessful, a doctor may consider switching you to alternative oral antifungals like terbinafine or fluconazole. Locally, switching to a steroid-free antifungal cream such as luliconazole or terbinafine is highly effective. I recommend consulting a dermatologist who can perform a skin scraping test to identify the specific fungal strain and tailor your treatment. In the meantime, keep the area clean and completely dry, wear loose-fitting cotton underwear, and avoid sharing towels.

For a widespread fungal infection covering a large area, topical creams alone are usually not enough. You will likely need oral antifungal medications, such as fluconazole, itraconazole, or terbinafine, to clear the infection from the inside out. Mild over-the-counter topical creams like clotrimazole or miconazole can help soothe local itching in the meantime. Please do not worry; this is highly treatable. However, because oral antifungals require a prescription and need to be selected based on your health history, it is important to consult a healthcare provider. They will confirm the diagnosis and safely prescribe the right treatment plan for you.

Dealing with a fungal infection for 15 years is challenging, but please be reassured that effective treatments are available. The most successful approach depends on the infection's location. For chronic cases, oral prescription antifungals like terbinafine, itraconazole, or fluconazole are highly effective as they treat the infection from within. Strong topical treatments containing clotrimazole or ketoconazole may also be used. To cure this permanently, it is crucial to visit a doctor for a skin scraping or culture to identify the exact fungal strain. This ensures a targeted treatment plan. Completing the entire prescribed course, even after symptoms disappear, is key to preventing recurrence.
