Ringworm near the outer vaginal area is a fungal infection called Tinea Cruris, and temporary relief with creams like Betnovate-GM happens because they contain steroids, which can worsen the infection over time. It is important to stop using steroid-mixed creams and continue a plain antifungal treatment regularly for at least 2-3 weeks, even after symptoms improve. Keep the area clean and completely dry, wear loose cotton underwear, and avoid tight clothing or moisture. Night-time itching is common due to warmth and sweating. Since your symptoms are persistent, it is best to consult a doctor for proper evaluation and guidance to ensure a complete and lasting cure.

If dandruff is spreading to the body with itching, it may be a fungal condition like Seborrheic Dermatitis or a superficial fungal infection. Instead of creams that are hard to apply over large areas, you can use antifungal lotions or medicated body washes for easier application, along with keeping the skin clean and dry. For the scalp, use an anti-dandruff shampoo containing ketoconazole or selenium sulfide 2-3 times a week, leaving it on for a few minutes before washing. Avoid oily products and scratching, as this can worsen the condition. If the problem is widespread or not improving, consult a doctor to confirm the diagnosis and guide proper treatment.

Itching and irritation on the penis for a few days may be due to infection or local irritation. Keep the area clean and dry, and avoid using harsh soaps or chemicals.
