Since antifungal creams like Candid (clotrimazole) and Tebina (terbinafine) haven't helped, your rash is likely not fungal. It could be an inflammatory skin condition, eczema, or a bacterial infection like erythrasma, which often leaves dark spots. Please stop using the antifungal treatments to avoid further skin irritation. For temporary relief from itching, you can apply a mild hydrocortisone cream or a plain moisturiser. However, because this has persisted for six months, I highly recommend consulting a dermatologist. They can properly diagnose the issue and prescribe targeted treatments, such as prescription-strength anti-inflammatory creams or antibacterial medications, to safely clear the rash and fade the dark spots.
