The cream you previously used contains a strong steroid, which provides temporary relief by reducing inflammation but can actually cause fungal infections to return and worsen once stopped. To treat this permanently, you should stop using steroid-containing creams. The recurrent itching is often due to a fungal skin infection, which is best treated with a targeted antifungal cream such as clotrimazole, miconazole, or terbinafine. I highly recommend visiting a doctor or dermatologist for a proper diagnosis. They can confirm the exact cause and prescribe the correct, targeted therapy. Meanwhile, keep the hip area clean, dry, and avoid scratching.
