Itching on Penis head and under foreskin

Hi, Few weeks back I saw red needle size dots on my penis head. That time i used fourdem for a day and the dots vanished away. Now again i got the same problem. Red dots and the under foreskin is reddish. So i consulted dermatologist and he diagnosed it as a zoon balanitis. he asked me to use emusone. I am using the same. First day of application i felt comfortable. The red dots are gone.But now i can still see the redness still there. Also i feel discomfort while sleeping as well as working.This maked itching.This makes mood swing. Also i can see a white skin like patch on the foreskin after using eumusone. But doctor said it is steroid withdrawl ( steroid withdrawl of Fourdem which is used only once 15days ago)  Please help me with this. This is 6th day after application of Eumusone-m cream.
