Burning and redness of the scrotum, though often called fungal, is usually a manifestation of irritation or eczema. Because steroid creams have also failed to clear you up, I suspect that most of the irritation is gone, and what you have left is a feeling of sensitivity and a sustained concern for redness that you really ought to ignore. My advice therefore is to stop using all medicated creams and to use instead only bland moisture lotions like Lubriderm or the equivalent. Keep this up until you see the dermatologist. Also, pay as little attention as possible to redness and tingling, as they generally mean little or nothing and subside gradually on their own.
Take care.
