Tocoderm NF Plus Cream you have been using contains a strong steroid. Using it daily for five years has likely caused skin thinning and a "rebound" itch whenever you stop. To cure this, you must break the steroid cycle. Please consult a dermatologist. They will likely transition you to a pure, steroid-free antifungal cream (like clotrimazole or miconazole) or prescribe oral antifungal tablets (such as fluconazole) to treat the actual infection. Keep the area completely clean and dry, and wear loose, breathable cotton clothing. Do not worry; this rebound effect is very common and entirely treatable once you switch to the correct, steroid-free therapy under medical guidance.

The main reason your infection is persistent is likely the use of steroid-containing creams. While they temporarily relieve itching, steroids weaken the skin's defence, allowing the fungus to flourish and resist treatment. To resolve this, stop all steroid creams immediately. Alternative oral antifungals like fluconazole or griseofulvin, paired with topical antifungals like luliconazole or amorolfine, are often effective. Keep the area clean and dry, wear loose cotton clothing, and wash laundry in hot water. Please consult a dermatologist for a skin scraping test to target the specific fungus. This is manageable and highly treatable with the right approach!
