Hi, Thanks for writing in. Its possible that you have another fungal infection which is now in the scrotum regions. Fungal infections affect moist areas where the skin remains moist and allows the fungus to grow. It is possible that the fungal infection in your penis shaft is treated but some of the fungi have now started growing in the scrotum. This causes itching and discoloration. Please trim your pubic hairs short and dry your genital area completely after bath. Wear cotton inner clothes and wash your genital region with warm water twice daily. Apply antifungal ointment to the area of itching and skin discoloration twice daily. You can use the same ointment which you have taken earlier. Avoid scratching the area as this will spread the infection. The itching should stop 3 days after starting application of anti fungal ointment and treating the condition might take a month if treatment is taken regularly. Skin will return to normal colour in few months.
