Thanks for writing to us.
From the description provided it could be a fungal infection(tinea), psoriasis
or eczema. So firstly the diagnosis has to be confirmed.
Now, you have already met a doctor and the condition has been diagnosed as fungal infection. Sometimes fungal infection does not respond to topical antifungal
alone. In such cases oral antifungal
is also prescribed. Also to reduce inflammation an antifungal can be applied topically in combination with steroid
Hope that helped.
