I Have Tinea Corporis Around My Belly Button And Tinea

I have tinea corporis around my belly button and tinea cruris from 2-3 years. It itches badly in both areas, also it is always red. I consulted a doctor and he prescribed several medicines including ketoconazone cream, itraconazole tablets, Keraglo AD shampoo, Moistron cream and Ronyglam lotion. There is improvement in condition but its not much. Plz tell whether these medicines are enough or do i have to take something else for better results...
