Small whitish patches around the vaginal opening may be caused by a mild fungal infection, irritation, or certain skin conditions, and they do not always cause itching or pain. Since you have already used a steroid-based antifungal cream, it is best not to continue using it without medical advice, as it may worsen skin conditions if used incorrectly or for too long. Keep the area clean and dry, avoid harsh soaps or tight clothing, and consult your doctor for a proper diagnosis and treatment.
